5 июн. 2016 г. · It is sin(x)cos(x)2 . Explanation: sec(x)=1cos(x). So we want to calculate. ddx1cos(x)=ddx(cos(x)−1). for the chain rule this is equal to. |
Compute the derivative: We know that. s e c x = 1 cos x. So we can find the derivative as. d d x s e c x = d d x 1 cos x. |
17 июл. 2019 г. · The derivative of sec(x) is sec(x) * tan(x). Here's how to derive it: Recall that sec(x) is the reciprocal of cosine, so sec(x) = 1/cos(x). |
