Integral of pythagorean type formula?
Integral of pythagorean type formula?
(OP)
Can anyone integrate this?
Integral(sqrt[((cosx)^2)+(x^2)]dx
It is like the integral of a pythagorean formula composed of 2 functions of x.
Thanks,

Are you sure that the equation is written correctly?
If you need the value of the integral over a specific range, try integrating numerically (using excel or similar).

I'll use numerical integration but I was wondering if anyone out there knew of a definite integral for this one.

MathCAD can, however, evaluate it for any range, and it seems to give real numbers for any real number input.

once you do this MathCad and Dervive can solve.

I think numerical methods is your best bet, which is probably what many of readers have suggested using canned software programs.
I'm going to keep at it, I like the abuse. Hopefully I can prove the answer in my own lifetime! :)
