The proof of this identity is very simple and like many other trig id. The denominator 1 + tan^2(x) = = =. When you divide the numerator (expression (1)) by the denominator (expression (2)), cos^2(x) cancels, and the remaining expression is , which you can rewrite = =.

1+ sec^2x is the same as 1+ (1/cos^2x) then you have to add them together by changing the denominator of 1 so it would be (cos^2x + 1)/cos^2x when you change 1+tan^2x it will come out as (cos^2x + sin^2x)/cos^2x at this point the answer should be obvious. $$\Rightarrow \boxed{\tan(2-\tan^{-1}2)=\dfrac{\tan 2-2}{1+2\tan 2}} $$ Become a member and unlock all Study Answers.
