2sin (2x)cos (x) + sin (2x) = 0. Factoring our the sin (2x): sin (2x) (2cos (x) +1) =0. Now using the double angle formula for sine: 2sin (x)cos (x) (2cos (x) + 1) = 0. So, sin (x)= 0, cos (x) = 0 or

- sin (3x) - cos (x) = 0 which I consider to be very odd! This is the same as: sin (3x) + cos (x) = 0 Changing cos to sin: sin (3x) + sin ( 90 - x) = 0 so that: sin (x + 45) = 0 or cos (2x - 45) = 0 T
