How do you differentiate 2tanx?
January 09, 2012 4:08PM
Coefficients can be removed when differentiating, i.e. d/dx 2tanx = 2 d/dx tanx
You should know that d/dx tanx = sec2x (either by differentiating sinx/cosx or by just remembering the derivatives of common trig functions, as it will come in handy).
So the answer is 2sec2x
