Integral of sin 3xcos 3xdx
Nettet8.6 Integrals of Trigonometric Functions Contemporary Calculus 4 If the exponent of cosine is odd, we can split off one factor cos(x) and use the identity cos2(x) = 1 – sin2(x) to rewrite the remaining even power of cosine in terms of sine.Then the change of variable u = sin(x) makes all of the integrals straightforward. NettetSolution: I = ∫ (sinx)4/3.(cosx)2/3dx I = ∫ (cosxsinx)4/3.cos2xdx ⇒ I = ∫ (tanx)4/3sec2x dx put tanx = t ⇒ sec2xdx = dt ∴ I = ∫ t4/3dt ⇒ I = t1/3−3 + c ⇒ I = (tanx)1/3−3 + c Questions from Integrals 1. If f (x) = ∫ 1x 4 −t2 dt, then real roots of the equation x− f ′(x) = 0 are J & K CET 2012 2. If f (x) = 2x∫ sinx cos(t3)dt, then f ′x is equal to

Nettet14. nov. 2024 · 2 I tried to solve ∫ sin 3 ( x) cos ( x) d x by setting it equal to ∫ cos 1 / 2 ( x) ( 1 − cos 2 x) sin ( x) d x and then making u = cos ( x) and d u = − sin ( x). I ended up with − 2 cos 3 / 2 ( x) 3 + cos 2 ( x) 2 + C but the book's answer is 2 cos 7 / 2 ( x) 7 + 2 cos 3 / 2 ( x) 3 + C Could you give a hint as to what I'm doing wrong?
