    That doesn't really look like an integral anyone can do. Is that actually the complete problem?

    it says find the equation of the tanget line at the given balue of x, x is 0 in this case. i found the slope to be zero but i dont know how to find the y value

    Then you don't want to integrate it. Just substitute x=0 into y=sin(sqrt(x^2+pi^2)) to find y.
