Evaluate the integral x 2 cos ( 2 x ) dx?

Just watch this video for having a deeper understanding as I am tired of typing much. Therefore, use the identity: cos2(x) (cos(2x) 1 2 to remove this power, giving the integral:  (xcos(2x 2  x/2. See this symbol: mathdisplaystyle int _a b f(x) dx/math is known as integral operator which is operated over a function which works on mathx/math. But still if you dont then first please read this answer as it will give you a feel about what you are doing. The second integral  x/2 dx is simple, integrating to x2/4. Here, we have to categorize the two functions seen in a question according to the rule of ilate. Therefore, we can name math"x math as mathI/math(first function) and math"cos(2x math as mathII/math(second function). Like or, share button! This method of integration is known as integration by parts and the rule discussed there is known as ilate Rule. Using the integral rule, we have, using the integral rule, we have, integration by Using Partial Fractions.

Can you take it from here? Well, first of all, you've forgotten some rather crucial parentheses. By the double angle formula, sin(2x) 2 sin(x)cos(x) int fracsin(2x)1 cos2(x)dx int frac2sin(x)cos(x)1cos2(x)dx, let u 1 cos2(x) du -2sin(x)cos(x) dx bstituting, we get: int frac2sin(x)cos(x)1cos2(x)dx int -frac1u. Here's my attempt: i know cos2 x cos2x 1/2 (from double angle cos formula) integral of (1 - cos2 x) * cos2 (x) dx integral of cos2 (x) - cos4 (x) integral of (cos2x / 2 1/2 ) - (cos(2x 2 1/2 cos(2x) /. I'm the other of the two guys who "do" homework. Reply With", 05:58 PM #2, re: integral of sin2 (x) * cos2 (x). Reply With", 08:38 PM #3 reply With", 09:18 PM #4 yes, thank you galactus and soroban! Side Note : You're a bit sloppy with your use of the differential notation (the ds).
