Well I thought since I just did that problem in my matrix theory homework that anyone else who googled it like I did would appreciate the hint versus just having the answer given to them. Well maybe most kids won't but I would have! :)

I know that this is a ridiculous amount of time after the questions was asked, but I thought I would help with the first question. as we all know with eigenvalues Ax=lambdax the easiest way I have found to show that A^(-1)x=1/lambda x Is to use matrix multiplcation to get A^(-1) on the right...

Thank you Thank you for the help everyone I completed the problems. :smile:

Homework Statement integral (t * csc^2 (t) ) dt Homework Equations The Attempt at a Solution t * -cot (t) - integral( 1 * -cot (t)) u= t dv= csc^2(t) du= 1 v= - cot (t) -t * cot(t) - ? I don't understand...

[FONT="Trebuchet MS"] does anyone know the antiderivative of cotangent or of arcsine? any explanation would be appreciated.
