Hence, evaluating the derivative of the function using the quotient rule yields `f'(x) = ( 2tan x/(cos^2 x))/((1 tan x)^2)` Approved by eNotes Editorial TeamPlease see below (1tan^2x)/(1tan^2x) = (1sin^2x/cos^2x)/(1sin^2x/cos^2x) = ((cos^2xsin^2x)/cos^2x)/((cos^2xsin^2x)/cos^2x) = (cos^2xsin^2x)/(cos^2xsin^2xSin^2 x cos^2 x = 1 Now left hand side = sec^2 x tan^2 x =1/(cos^2 x) (sin^2 x)/(cos^2 x) =(1 sin^2 x)/ (cos^2 x) = cos^2 x / cos^2 x =1 = RHS

1) π 6 I can see that my solution has odd multiples of π / 2, which should be discarded, but I thought of it only after checking the solutionFrom this formula we can derive tan(2x) as tan(xx) So tan(2x)= 2tanx/1tanxtanx We can always go for the longer approch from sinx/cosx to derive this formula K views
Next, it will be tan x to the power cot x, and in the third brackets, cos x/sinx into cos x/sin x into 1/cos^2x minus log tan x into cosec^2x Now we are canceling the cos x Then dy/dx equals tan x to the power cot x into cosec square x minus cosec square x into log tan x
