Homework Equations

i have to find the intergral of

sin squroot((x^2)+(pi^2))

The Attempt at a Solution

im stuch on what i am suposed to do, i have -cos for the intergration of sin but I am confused what i do with squroot and its content.

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

 

[camboguy]

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 don't know how to find the y value

 

[Dick]

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