Find the derivative of each of the following: $y = 5 \cos x + \cos 7x - \sin 3x - 1$ \(y = \sin 4x

Question

Find the derivative of each of the following: $y = 5 \cos x + \cos 7x - \sin 3x - 1$ $y = \sin 4x + 3x^2$ $\mathrm{f}(x) = 6 \sin (4x^3 - x) - 4 \tan (3x^2)$

Accepted Answer

(a) $-5\sin x-7\sin(7x)-3\cos(3x)$ (b) $4\cos(4x)+6x$ (c) $6(12x^2-1)\cos(4x^3-x)-24x\sec^2(3x^2)$
