Simplifying sin(2pi * f * t + -1pi) + sin(2pi * f * t + pi) = 0 Multiply ip * f ins(2fip * t + -1pi) + sin(2pi * f * t + pi) = 0 Multiply fip * t ins(2fipt + -1pi) + sin(2pi * f * t + pi) = 0 (2fipt * ins + -1ip * ins) + sin(2pi * f * t + pi) = 0 (2fi2npst + -1i2nps) + sin(2pi * f * t + pi) = 0 Multiply ip * f 2fi2npst + -1i2nps + ins(2fip * t + pi) = 0 Multiply fip * t 2fi2npst + -1i2nps + ins(2fipt + pi) = 0 2fi2npst + -1i2nps + (2fipt * ins + ip * ins) = 0 2fi2npst + -1i2nps + (2fi2npst + i2nps) = 0 Reorder the terms: 2fi2npst + 2fi2npst + -1i2nps + i2nps = 0 Combine like terms: 2fi2npst + 2fi2npst = 4fi2npst 4fi2npst + -1i2nps + i2nps = 0 Combine like terms: -1i2nps + i2nps = 0 4fi2npst + 0 = 0 4fi2npst = 0 Solving 4fi2npst = 0 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by '4'. fi2npst = 0 Simplifying fi2npst = 0 The solution to this equation could not be determined.
