Post #19

Alright ladies and gents, here goes nothing. Today i'll explain how to do integrals. Because everyone is going back and expaining derivatives..so, of course, let me do the exact opposite.

Now, the first thing you have to do is locate the problem.
Then, read the problem.
You may ask, is this an integral or a derivative. Well, before you ask that terrible question, you know it's an integral if it has a fancy looking S infront of it.
Next, predict a method of solving; since it's a integral...
Perhaps, you should remember what you learned in class.
Then, perform the steps which include: adding one to the exponent and dividing it by the coefficient.
Finally, simplify fully.

So, lets do it with a problem.

Locate, Read, Predict, Think about the Problem
S 2x^3 + 7x + 6

Solvinggg....
S 2/4x^4 + 7/2x^2 +6x

Simplifying fully...
S 1/2x^4 + 7/2x^2 +6x

And tada. There you have it. You have successfully completed an integral problem. Now, you might thing this is all fun and games, and really easy. But don't fool yourself, it isnt always going to be that easy..such as when substitution comes along. [which i STILL do not understand]. So, if anyone wants to take a wackin at trying to explain it to me, that'd be greattt...or probably not, because we don't have to do comments..so nevermind. hahha, i made a funny on accident!

I hope everyone had a good christmas and got everything they wanteddddd!!!
