it depends , but alot of the time when you have a variable with a power, you just add 1 to the power and divide all of that by what you get for instance :

becomes

Thank you... that helps alot... but what about if it's not to a power say 2/X^2

finding an anti derivative is based on these steps:

1) Known formula,which gives an immediate integral

now,when things get serious,you have to use at least one of those:

2)U substitution

3)Integration by parts

4)Partial Fractions

5)Trig substitution

6)complete the square

that`s about it i think - Jan 26th 2009, 06:14 PMLarrioto
You have to see it as

if you integrate, your 2 goes in front because it's a constant and you just have to apply the trick :

which is

=

there's no formula, but to find the integral

just add the exponent by 1, and then divide the part you integrated by your new exponent - Jan 26th 2009, 06:26 PMkatchat64
Ok then... how would you take the antiderivative of
