One of the hardest things about learning math and physics is having all the formulas you need ready. Do not worry! There are a few ways you can memorize the formulas you need. Reminders can help you remember the formulas. Understanding the components of each formula and what they mean may help you rebuild a formula, even if you don't immediately remember it. Take good care of your body by sleeping well and eating healthy food, so that everything you learn actually stays in your head!

To step

Method 1 of 3: Using reminders

1. Use an established reminder. Reminders have existed for a long time for some mathematical and physical formulas. Your teacher may have already used a few to teach you the formula. Use those mnemonics to memorize formulas you can't seem to remember.
   • For example, you may have learned the formulas for sine, cosine, and tangent of an angle with the mnemonic "SOS CAS TOA". Here is S.inus is the length of the Ounderstanding side divided by the S.oblique side, C.osine 'is the length of the aan underlying divided by the S.hypotenuse, and T.angens is the length of the Ounderstanding side divided by the aopposite.
2. Make your own reminder. Not every formula has a general mnemonic you can use. In that case, make your own! Use parts of the formula to tell a story or spell a word you can remember.
   • For example, if you want to memorize E = mc, you can do this by imagining that Donkeys (E) are afraid of mice drinking cola.
3. Use a memory palace. A memory palace is a specific type of memory aid that uses visual cues to help you remember things. You should always use the same location and "travel" through it, looking for the things that help you remember the formula.
   • Consider, for example, the house where you grew up. Suppose you are trying to remember that the area of ​​a circle is pi times the radius squared. You can remember this by thinking of the kitchen, where there was always a cake on the windowsill, with two roller pins next to it.

Method 2 of 3: Understand formulas

1. Break up the formula. If you focus on memorizing the formula, chances are you won't be able to memorize the formula for much longer. But if you understand every part of the formula and how those parts work together, it can be easier to remember the formula itself.
   • Suppose we say that speed is the amount of time it takes for an object to travel a certain distance. So to determine the speed, you need to know the distance the object traveled and how long it took to get there: so divide the distance traveled by the amount of time it took to get there. Knowing all this, you can find out that "speed = change in distance / change over time".
2. Take another look at what the formula builds on. Most physics and math formulas build on things you've already learned. If you have trouble remembering new formulas, revisit the ones that preceded them.
   • For example, suppose you have trouble remembering the vector speed formula, but you know that it is the speed of an object in a particular direction. Take a look at the formula for speed, which is distance over time. Then you know that vector speed is nothing more than speed with a direction.
3. Practice any formula. The more you practice each formula and enter different values, the more you understand how it works. Understanding how it works can help you memorize the formula itself.
   • Practicing each formula takes a little time, but it's worth it, especially if you have an important exam ahead or need these formulas for your further career.
   • You can find practice questions in your textbook, or search online for practice tests. If you're struggling to find additional questions to practice with, ask your teacher for some assignments.

Method 3 of 3: Take care of your body

1. Relax. If you are particularly stressed or concerned, you will not be able to learn the material and memorize those formulas with difficulty! Before you go to college, sit down at your desk. Take a deep breath and let each of your muscles relax.
   • If you find that it seems too much for you, put your work aside for a moment and take a deep breath again. Give yourself a break to relax a bit.
2. Eat a light snack. If you are hungry or thirsty while trying to study, you will get distracted. If you are distracted, it will be harder to concentrate and you probably won't be able to remember things. Keep something light to eat, such as fruit and some water, on hand while you study.
3. Exercise after your studies. It may sound a bit strange, but some exercise after your studies can help you remember formulas better. The endorphins your body releases during exercise help improve your memory, so go for a walk or a run when you're done studying.
4. Get enough sleep. It's important to get enough sleep before and after your studies so that your brain can remember what you studied. You should get at least eight hours of sleep a night in a room that is dark.
