What does SOH CAH TOA stand for?

Back

SOH CAH TOA is a mnemonic to remember the definitions of the trigonometric ratios: - SOH: Sine = Opposite / Hypotenuse - CAH: Cosine = Adjacent / Hypotenuse - TOA: Tangent = Opposite / Adjacent

What is the value of tan(45°)?

Back

The value of tan(45°) is 1, because the opposite and adjacent sides are equal.
