Click here👆to get an answer to your question ️ evaluate the following integral: This way you can reduce the integral from the sixth power of $\sin x$ and $\cos x$ combined to a trigonometric function of $6x$ using standard trig identities. A conventional approach to this problem would be to express the integrand as a product of their double angle counterparts. I = ∫ 0 π 4 cos 4 x d x ⇒ i = ∫ 0 π 4 ( cos 2 x) 2 d x.
∫ π 2 0 cos (2x) dx ∫ 0 π 2 cos ( 2 x) d x.
Evaluate the definite integrals`int_0^(pi/4 ) (sinxcosx)/(cos^4x+sin^4x)dx` updated on: Evaluate integral from 0 to pi/2 of cos (2x) with respect to x. Divide throughout by cos^4x in numerator it becomes (2tanxsec^2x) and denominator becomes (tan^4x + 1) now you can solve easily by substituting tan2x = u. Mathematically, we can write the integral of cos4x as, ∫cos4x dx = (1/4) sin4x + c, where c is the integration constant.this integral can be evaluated using the substitution method of integration and the formula for the integral of cos x.
