Question

Differential coefficient of cos(3x+7)^1/2

Answer 1

Answer:

Use the chain rule of differentiation to find derivatives of functions; examples with detailed ... f '(x) = (df / du) (du / dx) = () 1 / (2 √u) ) (2x + 2) ... Use the trigonometric formula sin (2x) = 2 sin x cos x to simplify f '(x) ... 2) l(x) = (3x 2 - 3 x + 8) 4
