Question

difrentiate (coshx) ​

Answer 1

Answer:

The Chain Rule states that to differentiate a composite function we differentiate the outer function and multiply by the derivative of the inner function. We can use the rules cos x = sin ( /2– x) and sin x = cos( /2 – x) to find the derivative of cos x. Find the derivative of f(x) = sin2x2.

However, this can be also done using the chain rule for differentiating a composite function: (cotx)′=(1tanx)′=−1tan2x⋅(tanx)′=−1sin2xcos2x⋅1cos2x=−cos2x sin2x⋅cos2x =−1sin2x......
