Secant 2 theta
WebFormula cot 2 θ = csc 2 θ − 1 The square of cot function equals to the subtraction of one from the square of co-secant function is called the cot squared formula. It is also called as the square of cot function identity. Introduction The cotangent functions are sometimes appeared in square form in trigonometric expressions and equations. Websin θ2 means to square θ, then do the sine function Example: 32° Using 4 decimal places only: sin (32°) = 0.5299... cos (32°) = 0.8480... Now let's calculate sin2 θ + cos2 θ: 0.5299 …
