Integrate this MF'er

sin^3(3x) Cos^4(3x)

here's what I got

-1/6 (1/5(cos^5(3x)-1/7(cos^7(3x)) + c

So want this expression make it into an integral right?

Ti-89 never don me no bad yup yup

[Teg2boo]

You all sucks at interweb

http://www.wolframalpha.com/input/?i=-1/6+(1/5(cos^5(3x)-1/7(cos^7(3x))+%2B+c+

copy paste, linky no worky

using the supplied link you a totally different answer.

i used to know how to do this, wtf. now im just lost lol

[92CXyD]

Well your answer is not right.

I tried doing it by hand I'm a little rusty. Looking at my tables of Integrals you will me using u substitution and a reduction formula. ;D

I have a degree in mathematics but I just usually use my trusty HP50g or Maple 11 program.

But that math link comes in handy.  ;D

I hate integrating trig functions.

I could do it, but I would probably have to double check a reference of some sort.

i lost you after integra

Let u=3x and du=3 dx

http://www.wolframalpha.com/input/?i=sin%5E3%283x%29+Cos%5E4%283x%29

makes sense the only problem I have is if your professor only wants you to use the integral table in your book.

In my old Calculus and Analytic Geometry 7th ed. it is #68 or #69.

I usually use Maple 11 for this so I can get the rest of my work done.  ;D

Haven't touched that shit since high school.

Wouldn't know where to start

Dont you know asians are better at math than you.  The answer is clearly cheeseburgers
