WebSolve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. 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 - …
