Answer 2

Integrating functions is one of the core applications of calculus. Sometimes, this is straightforward, as in:F(x) = ∫( x3 + 8) dx

In a comparatively complicated example of this type, you can use a version of the basic formula for integrating indefinite integrals:

∫ (xn + A)dx = x(n + 1)/(n + 1) + An + C ,

where A and C are constants.

Thus for this example,

∫ x3 + 8 = x4/4 + 8x + C.
