WitrynaThe two expressions on the left hand side are the same so you can add them giving: 3 ∫ sec 2 x tan 2 x d x = t a n 2 x + c. So simply divide by 3 to get your answer: ∫ sec 2 x tan 2 x d x = t a n 2 x 3 + c 3. Note that as c is an real number we could replace c 3 with c 2 to write the answer more neatly as: ∫ sec 2 x tan 2 x d x = t a n 2 ... WitrynaAre 2tanx and tan raise to 2x the same thing? Seriously? They are definitely not the same! As ‘tan’ is the abbreviation commonly used for the tangent function, I assume that, when you write ‘2tanx’, you mean: you want twice the tangent of some variable x.
