The following integral is taken from exercise 7.1 of james stewart calculus 7th edition early transcendentals
$$\int_0 ^te^s\sin(t-s)~ds$$
I tried integration by parts and got the answer as follows $-\frac{1}{2}[e^t+\cos(t)+\sin(t)]$. Please verify the answer and if it is wrong please mention the correct procedure
