i)

f'(x)=\cos(x+x^2)(1+2x)

ii)

f'(x)=\cos x+\cos(x^2)2x

iii)

f'(x)=\cos(\cos x)(-\sin x)

iv)

f'(x)=-\cos(\sin x)\cos x

v)

f'(x)=\cos\left(\frac{\cos x}{x}\right)\cdot \frac{x(-\sin x)-\cos x}{x^2}

vi)

f'(x)=\frac{x\cos(\cos x)(-\sin x)-\sin(\cos x)}{x^2}

vii)

f'(x)=\cos(x+\sin x)(1+\cos x)

viii)

f'(x)=\cos(\cos(\sin x))(-\sin(\sin x))\cos x
