In our lesson we had to learn about SOH-CAH-TOA, this should be used in almost anything maths in Game Design for rotation or movement purposes. There can also be scripts to show this.

## SOHCAHTOA

These ratios can be difficult to remember. You might easily get confused and not remember which side goes where. **SOHCAHTOA** is a mnemonic device helpful for remembering what ratio goes with which function.

- SOH =
**S**ine is**O**pposite over**H**ypotenuse - CAH =
**C**osine is**A**djacent over**H**ypotenuse - TOA =
**T**angent is**O**pposite over**A**djacent

With these properties, you can solve almost any problem related to finding either a side length or angle measure of a right triangle. SohCahToa can ensure that you won’t get them wrong.

## Radians

Below shows a definition of a Radian. It also gives us a explanation of what it is.
