Question

integral of x^3cosx^3dx from -π/4toπ/4​

Answer 1

Answer:

According to the theorem, the integral of cos(x) will be equal to the function that has cos(x) as its derivative plus a constant. ... By the fundamental theorem of calculus and the fact that the derivative of sin(x) is cos(x), we have that the integral of cos(x) is sin(x) + C, where C is a constant.
