Maths Tutorial: Trigonometry SOH CAH TOA (trigonometric ratios)
SOH CAH TOA is used to remember the trigonometry ratios; sine = opposite over hypotenuse, cosine = adjacent over hypotenuse, tangent = opposite over adjacent. This helps you work out unknown side lengths or unknown angles in a right-angled triangle. This video is a tutorial on how to apply this rule. I you like this video, please subscribe!
