My friend watched this video without any prior maths knowledge. If you are in the same position the O and A in SOHCAHTOA stand for opposite and adjacent.

So:
Sine = Opposite over Hypotenuse
Cosine = Adjacent over Hypotenuse
Tangent = Opposite over Adjacent

By over I mean divide

Opposite is in this case the smallest side of the triange (opposite the theta angle), and adjacent is the second largest side (adjacent to the theta angle)

This may seem obvious to some but the basics are essential.
