How to learn formulas effortlessly


Let’s first agree to the fact that memorising is a tiring process. It is no fun, and nobody really likes to do it. But most of the subjects such as Mathematics, Physics and Chemistry are loaded with formulas and equations that must be memorised. It might be hard for a lot of students to get all this up in their head. It can also confuse and take away a lot of their time. So, how can one find a solution for this dilemma? Luckily, we have listed down five extremely simple ways to etch any equations and formulas into the memory forever.

1) Mastering the concept

Understand the basic concept

Now, this is the best way to approach any formula. Rather than just memorising formulas, go behind the theory of it. Learn how it is proven. When you are crystal clear with the concept, you really don’t need to by heart anything. You can always rebuild the formula if you can’t recollect it all of a sudden.

2) Mnemonic devices

Use mnemonic devices during exam preparation

This is probably the most common approach used to memorise anything from formulas to definitions. There are numerous standard mnemonic devices that’s been in the use for years. You can also create your own mnemonic devices. For example, SOH CAH TOA is a mnemonic device used for learning formulas of sine, cosine and tangent.

Sin θ = Opposite/Hypotenuse

Cos θ = Adjacent/Hypotenuse

Tan θ = Opposite/Adjacent

3) Make charts or small notes


Create charts or small notes on every formula and if you can take a look at it daily, these formulas or equations will get engraved into your memory pretty quickly. However, this is a tiring process and often than not requires a lot of time.
