How do you integrate ?

In order to integrate an algebraic term, such as 8x3 + 4, one must first take the power of the first term and increase this by 1, getting 8x4. Secondly, divide the coefficient on x by the new power, in this case 8/4. Resulting in the first term being 2x4. Then, do the same to the second term. Here, the number 4 is technically 4x0, but of course, x0=1. Hence, 4x1=4. So again, 4x0 becomes 4x1. Then divide 4 by 1, which gives 4. therefore the second term is 4x1. Thus, the integral of 8x3 +4 is 4x4 + 4x + C. C being a constant that can be derived when limits are placed on the integral. Here is the formula for integration: Integral of un = un+1 /(n+1) + C ,
