WebFirst of all, you can conclude that: (1+tanx)2 = (1+ cosxsinx)2 = ( cosxsinx+cosx)2 = cos2x1+2sinxcosx ... Trying to simplify this expression using trig identities. [closed] tanx−11−tan2x = −(1−tanx)(1−tanx)(1+tanx) = −1−tanx Please check the answer carefully-there must be a mistake somewhere. Edit: If the denominator is tanx+1, ... WebHere are the steps for deriving the arctan (x) derivative rule. y = arctan (x), so x = tan (y) dx ⁄ dy [x = tan (y)] = sec 2 (y) Using sum of squares corollary: sec 2 (y) = 1 + tan 2 (y) tan 2 (y) = x 2, so dx ⁄ dy = 1 + x 2 Flipping dx ⁄ dy, we get dy⁄dx = 1⁄(1 + x2) Derivative of Arctan Example Problems Derivative of Arctan (2x)
