Derivative of Cos xThe differentiation of cos x is the process of evaluating the derivative of cos x or determining the rate of change of cos x with respect to the variable x. The derivative of the cosine function is written as (cos x)' = -sin x, that is, the derivative of cos x...
Calculating (√π2)2:(√π2)2=π2Now substituting this into the cosine function:cos(π2)=0Thus, the entire expression becomes:dydx∣∣∣x=√π2=−2(√π2)⋅0⋅sin(sin(π2))=0 Final AnswerThe derivative of cos(sin(x2)) at x=√π2 is:0 Show More ...
The derivative of the cosine function {eq}\cos(x) {/eq} is {eq}-\sin(x) {/eq}. If we want to incorporate the chain rule into the trigonometric derivative {eq}\displaystyle \frac{\mathrm{d}}{\mathrm{d}x} \cos(x) = -\sin(x) {/eq}, then we can utilize: {eq}\displaystyle...
