**soh**:

**S** in = **O** pposite over **H** ypotenuse

**cah**:

**C** os = **A** adjacent over **H** ypotenuse

**toa**:

**T** an = **O** pposite over **A** djacent

These are a set of mnemonics to help remember how to derive the basic trig functions for a (non-right) angle of a right triangle. (They only apply to right triangles).
