YO WHO MESSED UP NOVEMBER BUT IS WITH ME TO MAKE DECEMBER THE MONTH THAT THEY LOSE OR AT LEAST MAINTAIN

Hello, tumblr!

Today, I’m going to talk about AP Calculus! It has a reputation as one of the hardest AP courses, not without desert; it is heavy with concepts and requires a high degree of proficiency in all the math that comes before it. It is also enormously useful for a variety of fields, from architecture to medicine, and can be a lot of fun to do! Some tips:

Prepare

Most AP Calc courses come after a substantial list of prerequisites: Algebra 1 and 2, Geometry, Trigonometry, and whatever your school calls the mish-mash of topics falling under pre-calculus. It is imperative to be comfortable with these when you start; calculus uses all of them.

Specifically:

Know. The. Trigonometric. Circle. Know it like the back of your hand (if you are someone who studies each detail of your hand carefully like the weirdo who came up with this saying)

Make sure you know the trigonometric identities too, back and forth.

You will need the formulas from Geometry. These aren’t as hairy as the trigonometric ones imo, but still good to know so you don’t have to relearn them later.

Make sure you are comfortable with algebraically changing expressions from one form to another. Factoring and reducing expressions will be super important.

If you have a hard time with any of these, it’s ok; you can review them! If you find that you have forgotten anything you need during your course, see if you can find some excercises in it online or in a book, and do a few so that you are comfortable with it.

Practice

AP Calc involves some proofs, but most of the course is about learning how to do specific types of operations. The best way to prepare is to just do the problems you are assigned for homework, then do more as time passes or if you have a hard time with a particular one.

Memorize formulas as they are introduced. Review them often. Do problems with them.

If you do not understand a concept:

Try to break down why. Do you understand part of it? Write down what you know. See what it is that is stopping you.

Try drawing a picture. Label it. See if you can relate your problem to the visual geometry.

Try working a problem. See where you stop understanding it. Ask yourself why you are doing each step. See if you can explain to yourself.

Look at a worked problem. Explain each step to yourself. See where you stop understanding.

If there a proof involved? Work through the proof, making sure you understand each step. This can give you a solid foundation.

Go to your teacher or a friend with specific questions.

The FRQs and MCQs from previous tests are a goldmine. Do every one you can get your hands on. For FRQs, compare your answers to the model answers given on the College Board website. Mark everything you do wrong. Try to remember it and do it right next time you do a similar problem.

FRQs are great because they tend to incorporate multiple concepts, giving you practice, and they also follow similar patterns. Getting used to those patterns is really helpful.

The Test

Do some full practice tests. Time yourself. Note the concepts you get wrong and review them. Ask someone about things that give you trouble.

Make sure you know all your formulas well.

Make sure you can do everything you will need to with your calculator.

Part of the test is no-calculator. Make sure you can do the sort of problems which appear there without your calculator.

When you take the test:

Sleep.

0/10 do not recommend late night cramming the night or two before the test.

Change your calculator’s batteries. Just so you’re certain it won’t die on you.

Have something to drink on you.

On the MCQs, skip problems you can’t do quickly and come back to them. I recommend:

Doing all the easy problems first. The ones that you get instantly. Just read the rest.

Come back and do the ones you need some time for. Ignore any if you have no idea how start or take a lot of time.

Come back for these on the third pass.

They’re all worth the same amount, so don’t worry about specific ones; just get as many as you can right.

Show. You. Work. On the FRQs. Write down everything you can.

If you don’t know how to do the first part of a problem, but the second part relies on it, just pick a number you think is reasonable for the answer to the first part, and use it. You can still get credit for the second part if you use that number correctly.

Don’t stress out too much. Even if you feel terribly, it is quite possible that you did will.

For illustration, I took BC, and I literally cried after the test, because I thought I did terribly. I got a five. The percentage you need to get right to do well is low, and how you feel does not predict how you do.

Take a bit of time for yourself afterwards. It’s going to be May. The weather will be beautiful. Breathe it in. :)

ana buddy?

i’ve recently had a very bad binge that ended up with me gaining 5 pounds, and i need someone to help me through it or prevent me from doing it again /: i’ll be here for you, you’ll be here for me :D i got you pal! plus, it will be nice having someone you can trust.

must be at least two of these things:

13 years or older

5’4 or under (im like 4’11)

have a close sw and gw to mine (sw: 155 gw: 115)

here’s some stuff about me:

i don’t work out (except for school gym)

i eat 1,000 cals a day, but i’m trying to reduce it

i prefer to send sweetspo, but i can do meanspo

i am a student, so i won’t be able to respond for a chunk of the day. i’ll get to you as best as i can!

i love bts :)

“I Send You Safety” Spell

A spell to send a friend or loved one protection and safety.

You Will Need:

❀ Salt ❀ Rosemary ❀ Angelica ❀ Dandelion Fluff ❀ Blue Lace Agate, Carnelian, or Garnet ❀ Name of your friend on a slip of paper ❀ White Sachet

Steps:

❀ Fill your sachet with the herbs, friend’s name and piece of crystal of your choice

❀ “I send you protection from all that may harm you, I send you the wish of safety, I send you the energies to keep you out of harms way.”

❀ Tie your sachet shut and gently kiss it it focusing on your desires to send your friend protection

❀ place your sachet in a window, if you can crack the window open to help send the energies to your friend. 

So, cauliflower.

Cauliflower is 25 calories for 100 grams. The only thing I ate today was 200 grams of cauliflower and I feel like I ate a full meal, all for 50 calories. I put garlic, salt, and pepper on it and put it in the oven till it’s crispy. It’s AMAZING!!! Why have I not discovered this before?

moon powder

sooo i recently dropped my selenite sphere :( which was very upsetting. i saved all of the pieces and had been wondering how to best use them. i ultimately decided to make a powder.

selenite- purification, removes blocks to healing, angelic protection

eucalyptus seeds/ leaves- healing/protection/purification

jasmine- love/money/prophetic dreams

marshmallow root powder- protection/psychic powers/purification/love

these were the ingredients i decided on. i ground them all together, beginning with the selenite because it was the most difficult + i said a prayer and imagined my personal intentions for the powder. every ingredient i used is associated with the divine feminine, the element of water, and the moon, making it a super potent powder.  i’m not going to be using this as a bath powder, i’ll most likely be using it in moon rituals/candle magik/floor washing etc. also, it smells nice and looks lovely :)

[[this would also work as a fertility powder. both selenite and marshmallow root powder are associated with fertility. also, the addition of the eucalyptus seeds, symbolizing birth/fertility]]

31 calorie “cinnamon roll”

(not actually a cinnamon roll but it tastes just like it)

here’s how:

1 tbsp of white flour (28 kcal) 1 tbsp of water 1 tbsp of 0kcal sweetener ½ tsp of cinnamon (3 kcal)

mix in a bowl or a mug or whatever and put in microwave! it tastes really good and helps if you’re craving something sweet.

AP Chem summary: Chapter 1

1.1

Chemistry: the study of composition, structure, properties, and changes of matter.

Composition of matter relates to the kinds of elements it contains 

Structure of matter relates to the ways the atoms of these elements are arranged 

Property: any characteristic that makes a sample of matter unique 

Molecule: an entity composed of two or more atoms with the atoms attached to one another in a specific way. 

1.2 

States of Matter: the three physical states matter exists in; gas, liquid, solid

There are two types of pure substances: 

Elements: has a single kind of atom and is represented by a chemical symbol (basically anything on the periodic table of elements) 

Compounds: composed of two or more elements joined chemically 

The Law of Constant Composition/ The Law of Definite Proportions

The elemental composition of a pure compound is always the same 

Mixtures: have variable compositions and can be homogeneous mixtures (solutions) or heterogeneous mixtures 

1.3 

Physical and chemical properties can be used to identify a substance 

Physical change: matter does not change its composition (ex: Changes of state; gas to liquid, etc)  Chemical change (Chemical reaction): substance is transformed into a chemically different substance  Intensive properties: independent of the amount of matter examined (internal qualities)  Extensive Properties: relate to amount of substance present (external qualities)  Scientific Method: dynamic process used to answer questions about our physical world; can lead to scientific laws (general rules that summarize how nature behaves) Makes use of hypotheses (tentative explanations) which can be tested and refined into theories that can predict the results of future observations and experiments.

1.4 

Measurements in chem are made using the metric system and SI units. 

length- meter (m), mass- Kilogram (kg), time- second (s).  

Kelvin = Celsius + 273 Celsius = (5/9)(Fahrenheit - 32)  Density = Mass / Volume 

1.5 + 1.6 

All measured quantities are inexact to some extent 

Precision: how closely different measurements of a quantity agree with one another 

Accuracy: how well measurement agrees with the accepted or “true” value 

Significant Figures: one estimated digit, the last digit of the measurement. Certain rules must be followed. 

Dimensional Analysis: a problem solving technique where units play a major role within the calculation using conversion factors (ratios constructed from valid relations between equivalent quantities)
