Differentiate each of the functions w.r. to x in
x\textsuperscript{2} sinx + cos2x

Answers (1)

This question will involve the concept of both chain rule and product rule

\\Given \: \: that\: \: y=x^{2}\sin x+\cos 2x \\ \\ \frac{dy}{dx}=\frac{d}{dx} \left( x^{2}\sin x \right) +\frac{d}{dx} \left( \cos 2x \right) \\ \\ =\sin x\frac{d}{dx} \left( x^{2} \right) +x^{2}\frac{d}{dx} \left( \sin x \right) +\frac{d}{dx} \left( \cos 2x \right) \\ \\ =2x\sin x+x^{2}\cos x-2\sin 2x \\ \\
