d/dx integral from o to x of function cos(2*pi*x) du is

first i do the integral and i find the derivative right.

by the fundamental theorem of calculus, if there is an integral from o to x, don't i just plug the x in the function.

the integral of the problem is cos*2*pi*) is just cos(2*pi*x) right or is that wrong. then i find the derivative.

I'm not sure. I think it's sin(2pi), but you can check out calc101 (google it) for help..?

That's the same as the integral of sin^2 x dx. Use integration by parts. Let sin x = u and sin x dx = dv v = -cos x du = cos x dx The integral is u v - integral of v du = -sinx cosx + integral of cos^2 dx which can be rewritten integral …
