OT: Random Math Question
 
im wondering if anyone knows this. I've come across a potential factor of input function I would like to use in my paper, but I forgot my freshman calculus.



anyone know how to integrate


(1 + cosx)^(1/2)

and ( 1 - cosx)^(1/2)


any help will be appreciated.

my high school precal is worthless for this stuff...

Im taking calculas senior year (next yr) maybe I can get back to you then?

Usually, the trick is to just cancel everything out OR claim it is undefined. lol

You need a special formulae for that, they have tables or something for them. Those are improper integrals I believe.

That formula turns into (1/2)(U)^(-1/2) U=1+cos
then the 1+cos turns into -sin.
(1/2)(-sin)^(-1/2) easy!:rockon:

Because Math is a very important subject for many different majors?

what is integrating?

Opposite of differentiating.

re:
 
nvm I figured it out. i had to use the tan(x/2) substitution.

whatever...

inverse

adj [in vrs, n vrs]
1. opposite or reversing: opposite to or reversing something
2. mathematics involving oppositely affected variables: involving two variables that are in a mathematical relationship where, when one increases, the other decreases and vice versa

yeah I know, I'm just being an ass. I had a prof once that got all upset about people using opposite and inverse interchangeably, so I just thought of him when you said opposite

Basketball and math go together like tacos and chinese people.

Stupid salesman, nobody expects you to know a thing about math. You got a $400,000 home and a Cadillac with $40,000 a year. Simple arithmetic would have helped you evade such horrible lies.
