Find the derivative of each of the following with respect to $x$. \(y = 5 \cos x + \cos 7x - \sin

Question

Find the derivative of each of the following with respect to $x$. $y = 5 \cos x + \cos 7x - \sin 3x - 1$ $y = \sin 4x + 3x^{2}$ $y = \sin 4x - \cos 5x - 6x^{3}$ $y = 6x^{5} - \cos 5x + 4$

Accepted Answer

(i) $-5\sin x-7\sin 7x-3\cos 3x$ (ii) $4\cos 4x+6x$ (iii) $4\cos 4x+5\sin 5x-18x^2$ (iv) $30x^4+5\sin 5x$
