\int \frac{\sin x}{\sin (x-\alpha)} d x

=A x+B \log \sin (x-\alpha)+C

, then the value of

(A, B)

, is

View answer and explanation

Correct option: B

(\cos \alpha, \sin \alpha)

Option B (

\cos \alpha, \sin \alpha

) is correct because, after simplifying the integral using trigonometric identities, the coefficients of

x

and

\log \sin(x-\alpha)

are

\cos \alpha

and

\sin \alpha

respectively.
