Ahh. Thanks for your suggestions, they made me re-track my steps. And yep, I left out the part that the whole fraction is under a square root as well :-p That changes things a bit! Substituting x with u2 seems to do the trick now! Phew :redface:

Homework Statement Hi! In an assignment I have reached an integral that has the form: \int\frac{A+Bx+Cx^2}{Dx+Ex^2} where A-E are constants, the integration variable is x and the limits are 0 to 1. I'm supposed to remove the singularity at x=0 by substitution. A-E have values but they're...

Umm... it's a square matrix, does that mean that we can decide the square root? :P Like I said, I haven't really done anything like this before. If anyone can recommend some online reading (preferrably with examples of calculations) about solving matrix equations it would be much appreciated...

Homework Statement Okay. So I have an equation: ABA + BAB = 2I where A and B are square nxn-matrices and I is the identity matrix. From this, I am supposed to find a way to express B as a function of A (given that A is close to I). So B = F(A), and it is also given that F(I) = I. Homework...
