Integral of tan^2 (x) \square! We have inttan^2(2x)dx Recall that, through the Pythagorean identity, tan^2(x)=sec^2(x)1 =int(sec^2(2x)1)dx Split up the integral =intsec^2(2x)dxintdx =intsec^2(2x)dxx Now, let u=tan(2x) This means that du=2sec^2(2x)dx =1/2int2sec^2(2x)dxx =1/2intdux =1/2uxC =1/2tan(2x)xCX = t , then the integral reduces to ∫ sin 3 x cos 2 x d x = ∫ − ( 1 − t 2) t 2 d t This can easily be solved Share edited May 15 '14 at 1455

Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals For math, science, nutrition, historyAs there is no way to immediately integrate tan^2 (x) using well known trigonometric integrals and derivatives, it seems like a good idea would be writing tan^2 (x) as sec^2 (x) 1 Now, we can recognise sec^2 (x) as the derivative of tan (x) (you can prove this using the quotient rule and the identity sin^2 (x) cos^2 (x) = 1), while we get x when we integrate 1, so our final answer is tan13 The Fundamental Theorem of Calculus;
