integral of sin squared x

Let us learn about integral of sin squared x
1st convert sin-squared-x to its double-angle identity: 1/2[1-cos (2x)] & then integrate which expression by conventional process to obtain the solution:
x/2 - sin(2x)/4
The integral of sin x2 is one of the Fresnel Integrals. If F(x) = sin x is an function & the derivative of function with respect to x is f(x) = cos x , then we call the integral of f(x) with respect to x is F(x). In trigonometrically term like sin, cos, tan also can be performed in integral calculus.
i.e., ⌡cos x dx = sin x + c, where c is constant.
In our next blog we shall learn about role of students in disaster management I hope the above explanation was useful.Keep reading and leave your comments.
