Question

Evaluate this integral
class XII mathematics​

Answer 1

Answer:

$\boxed{ \red{\bold{(x + a)cos \: a - sin a \: log \: sin \: (x + a) }}}$

Step-by-step explanation:

Here we use substitution method ,

Let

=> x+a=t or x =t-a

and

=> dx=dt

Put the value in given question ,

we get

$\int \: \frac{sin(t - a)}{sin \: t} dt$

And we know that ,

● Sin(A-B)= SinA cosB- Cos A Sin B
