 Question 302828: 3cos^2 2x - 2sin^2 2x = 2 - 4sin2x find all the angles between 0degrees to 180degrees inclusive which satisfy equation --x-x-x-x-x-x-x-x-x-- express 1/ (x-3)(2x +1) as partial fractions hence evaluate (cant really draw it out but.... evaluate definite integral 7 on top, 4 below. 1/(x-3)(2x +1) Answer by Fombitz(13828)   (Show Source): You can put this solution on YOUR website!Let and to reduce the clutter, Remember that Substitute, You can factor, Two solutions: . . . I leave those to you to complete. . . . Partial fractions. Multiply by Leads to two equations, 1. 2. Multiply eq.1 by 3 and add the two together to solve for A. Then use either equation to solve for B. If you integrate you'll get INT= evaluated between and . I leave those to you to complete.
