WebTo solve the integral, we will first rewrite the sine and cosine terms as follows: II) cos (2x) = 2cos² (x) - 1. = 2sin² (x). = eᵡ / sin² (x) - eᵡcot (x). Thus ∫ [ (2 - sin 2x) / (1 - cos 2x) ]eᵡ dx = ∫ [ eᵡ / sin² (x) - eᵡcot (x) ] dx. This may be split up into two integrals as ∫ eᵡ / sin² (x) dx - … Web\lim _{x\to 0}(x\ln (x)) \int e^x\cos (x)dx \int_{0}^{\pi}\sin(x)dx \sum_{n=0}^{\infty}\frac{3}{2^n} cos(2x)=1-2sin^2(x) en. image/svg+xml.
