comment How do I integrate $\frac{\sqrt{1-k^2\sin^2 x}}{\sin x}$
@Jean-ClaudeArbaut Thanks for this reference. Why'd in physics I didn't encounter the one's, that can be expressed with elementary functions?

@Jean-ClaudeArbaut Maybe, as a physicist mine elliptic integrals are one, two, three complete/incomplete integrals.
