Answer 3

Oh crap, ireadit as arctan.

My bad x.x

Answer 5

Its okay, you described the concept good :)

Answer 6

Sorry about that.

Answer 7

its okay :))

Answer 8

arcsinx derivative is \[\frac{ 1 }{ \sqrt{1-x^2} }\]

Answer 9

\[\frac{d}{dx}( \sin^{-1}(x)) = \frac{1}{\sqrt{1-x^2}}\]

Answer 10

Once again, chain rule here :P

Answer 11
