Find the derivative of each of the following: \(y = 3x^2 - \tan\left( \frac{\pi}{3} - \frac{x}{3} \r

Question

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

Accepted Answer

(a) $6x+\frac13\sec^2(\frac{\pi}{3}-\frac{x}{3})$ (b) $21x^2+\frac{2\pi}{5}\sin(\frac{\pi}{5}x-3)$ (c) $12\cos x\cos(3x)-4\sin x\sin(3x)$
