xy'+y= sinx IVP is y(pi)=0

My attempt:

y' +y/x = sinx/x

Finding the I.F

e^$1/x * dx = e^lnx

I.F is x

Muliply all the equation by x

xy' + y = sinx

Restate the equation

(x*y)' = sinx

xy = -cosx + c

y = -cosx / x + c

I think i have done right so far, but I dont know how to to evaluate it with the

values look:

0 = - cos pi / pi + c ??? what How do i evaluate that?
