How do you integrate cos2x? Yahoo Answer

  1. The integrand simplifies; cos((pi))=-1 and the sum of the squares of the sine and cosine of any angle=1, so the integrand becomes x^2+2+2x^-2. The integral is x^3/3+2x-2/x+c where c is constant of integration
  2. Using the formula for integration by parts, we have \[\int {\left[ {f\left( x \right)g\left( x \right)} \right]dx = f\left( x \right)\int {g\left( x \right)dx – \int {\left[ {\frac{d}{{dx}}f\left( x \right)\int {g\left( x \right)dx} } \right]dx} } } \]

What is the integral of (cosx)^2? Socrati

  1. g that the integrand is: ∫ 75sin^3(x)cos^2(x) dx. If so, note that the power of sin(x) is odd and the power of cos(x) is even, so we need to pull out a factor of sin(x) from the integrand and "absorb" it into the dx term as follows: ∫ 75sin^3(x)cos^2(x) dx = 75 ∫ sin(x)sin^2(x)cos^2(x) dx = 75 ∫ sin^2(x)cos^2(x) [sin(x) dx] = 75 ∫ cos^2(x)[1 - cos^2(x)] [sin(x) dx], by the Pythagorean Identities. Now, if we apply the substitution u = cos(x) ==> du = -sin(x) and -du = sin(x) dx: 75 ∫ cos^2(x)[1 - cos^2(x)] [sin(x) dx] = 75 ∫ u^2(1 - u^2)(-1) du = 75 ∫ u^2(u^2 - 1) du, since -(1 - u^2) = -1 + u^2 = u^2 - 1 = 75 ∫ (u^4 - u^2) du, by multiplying through = 75[(1/5)u^5 - (1/3)u^3] + C, by integrating with the Power Rule = 15u^5 - 25u^3 + C, by multiplying the 75 through. Therefore, back-substituting u = cos(x) yields: ∫ 75sin^3(x)cos^2(x) dx = 15cos^5(x) - 25cos^3(x) + C. I hope this helps!
