Sec2y dy dx = 1. Since tany = x 1 and √12 +x2 = √1 +x2, sec2y = ( √1 + x2 1)2 = 1 + x2. The inverse tangent function is written as tan − 1.

D/Dx Of Tan^-1 I think he originally intended to do this: ( x) in inverse trigonometry, where x represents a real number. Since tan y=x, the tan ratio opposite/adjacent tells you that your opposite side is x and adjacent side is 1. ⇒ dy dx = 1 1 + x2.
