Homework Statement



It should be fairly easy according to classmates, yet its definitely been a while since I've had calc.

Took a pic of the problem.

Sorry the image is a little dark, it says find the integral of the first one, by evaluating the integral of the second one. ?

The Attempt at a Solution



This isn't really a homework assignment, I have notes scattered throughout. Figured I'd post it in this section anyway, I'm really just trying to remember how to do half this stuff.

THANKS!

I'm not sure which question you wanted help on.

Do you remember how improper integrals are defined?

Try integration by parts on the first question and see if you can find a general formula for the integral?
 
Thanks I'll definitely check it out.

Sorry the image was a little dark, its one question. It says find the integral of the first one, by evaluating the integral of the second one. ?
 

Thread 'Prove that the integral is equal to ##\pi^2/8##'

Prove $$\int\limits_0^{\sqrt2/4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx = \frac{\pi^2}{8}.$$ Let $$I = \int\limits_0^{\sqrt 2 / 4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx. \tag{1}$$ The representation integral of ##\arcsin## is $$\arcsin u = \int\limits_{0}^{1} \frac{\mathrm dt}{\sqrt{1-t^2}}, \qquad 0 \leqslant u \leqslant 1.$$ Plugging identity above into ##(1)## with ##u...

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
