Find the derivatives of the functions at the indicated points 2 cos x at x = \( \dfrac{\pi}{2}\)
Given:
f (x) = 2 cos x
By using the derivative formula,
Derivative off (x)= -2
Differentiate with respect to x xn loga x
Differentiate with respect to x xn tan x
Differentiate with respect to x x2 ex log x
Differentiate with respect to x x3 ex
Differentiate with respect to x x3 sin x
