The value of the integral $∫$ \left(\dfrac{sin x}{x}\right)^{6} $\left(\dfrac{xcosx - sin x}{x2}\right)dx$ is

(where, $c$ & is an arbitrary constant)

Options

A $\dfrac{\sin x}{x} + c$
B $\dfrac{\sin x}{x^{2}} + c$
C $\dfrac{sin^{7}x}{x^{7}} + c$
D $\dfrac{sin^{7}x}{7x^{7}} + c$

Correct answer

D. $\dfrac{sin^{7}x}{7x^{7}} + c$

Step-by-step solution

Put

\dfrac{\sin x}{x} = t .

Then,

I = ∫ t^{6}dt = \dfrac{t^{7}}{7} + c
