# SOHCAHTOA

SOHCAHTOA is a very useful mnemonic that can help students remember the sine ratio, cosine ratio, and the tangent ratio of the three basic trigonometric functions sine, cosine, and tangent.

SOH : Sine = Opposite / Hypotenuse

CAH : Cosine = Adjacent / Hypotenuse

TOA : Tangent = Opposite / Adjacent

Below, we show a nice figure that will help you greatly to remember sohcahtoa. Opposite means opposite to the angle θ and adjacent means adjacent or next to the angle θ.

You could also use the following mnemonic to remember the trigonometric ratios.

" Some Old Hog Came Around Here and Took Our Apples."

## An example showing how to use sohcahtoa Sin(θ) = 6/10 = 0.6

Cos(θ) = 8/10 = 0.8

Tan(θ) = 6/8 = 0.75
