Use the double angle formula: sin(a) + sin(b) = 2 sin[(a+b)/2] cos[(ab)/2] let a = 3x, and b = x, so we have sin(3x) + sin ( (a) -2 ln |x| + ln(x2 + 1) + arctan(x) + C. (b) ln(2 +. /. 3) - ln(. /. 2 + 1). (c). 1. 2 sin(2x) -. 1. 6 sin3(2x) + C. (d) -. 1. 2 x cos(2x) +. The b-type letter, "β", is called "beta", which is pronounced "BAY-tuh". Content Continues Below.
