Use mnemonics, to try to memorize formulas you have a hard time with. Mnemonics are techniques for remembering anything more easily. For instance, in any right-angled triangle, for any angle:

The sine of the angle the length of the opposite side
                                   the length of the hypotenuse

The cosine of the angle = the length of the adjacent side
                                      the length of the hypotenuse

The tangent of the angle = the length of the opposite side
                                      the length of the adjacent side


This formula is often remembered as, ‘soh cah toa‘. So, you can learn the formulas for sine, cosine, and tangent of an angle with it, by shortening it to: “SOH CAH TOA.”

In “SOH CAH TOA: Sine is the length of the Opposite side over the length of the Hypotenuse. Cosine is the length of the Adjacent over the length of the Hypotenuse. And Tangent is the length of the Opposite side over the length of the Adjacent.
