### Ellipse Integral

$$\int\limits_{a}^{b}$$ $$a/(1-b*cos(x)) / sin(arctan((-1+b*cos(x))/(b*sin(x))))$$

Help to solve this problem

a and b are constants

### Re: Ellipse Integral

I have never been able to figure out what "a/b/c/d" means! Is it $$\frac{\frac{a}{b}}{\frac{c}{d}}$$ or $$\frac{a}{\frac{b}{\frac{c}{d}}}$$ or ...?
