Find the derivative: (do not simplify) f(x) = sec(sqrt(1+(2x/tanx))) Is this the correct answer? tan (sqrt(1+(2x/tanx))) sec (sqrt(1+(2x/tanx)))1/2(1+(2x/tanx)))^-1/2 ((2tanx-2xsec^x)/(tan^2x)) sorry I don't know how to make this look any better.

Why is it x^2 in the second part of the subtraction.. before taking the derivative isn't the numerator: (2x)'(tanx) - 2x(tanx)' ? I do not quite understand...
That was a typo.
Hello, tmas! . Correct! . . . Good work!
