I don't know how to integrate this sin(x^2) . Can someone show me how to? Thanks

@Dollesin Joseph Use this result: \(\displaystyle \int\limits_0^{\infty} \sin(x^n) dx = \sin(\frac{\pi}{2n})\frac{\Gamma(n+1)}{\Gamma(n)}\)..

that is only for these limits... other wise mention limits

You can't express this integral in terms of elementary functions. This integral is known as the Fresnel integral. You can express the integral as a power series instead: \(\displaystyle S(x) = \int_0^x \sin(t^2) \, dt = \sum_{n=0}^\infty (-1)^n \frac{x^{4n+3}}{(2n+1)!(4n+3)} \).
