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.

@Jean-ClaudeArbaut It's definitely not an elliptic integral. It's actually can be expressed as a primitive functions.

comment Quotient rule, one sign wrong
@Paul Nope, you are correct, and the book answer is wrong.

comment Why is the result of $-2^2 = -4$ but $(-2)^2 =4$?
Because first one is $-(2^2) = -(2\cdot 2) = -4$ and the second one is $(-2)^2 = (-2)\cdot(-2) = 4$?
