Meaning of your asking for if x=2sin2θ and y=2cos2θ+1 then x+y is ? solving this math problem is easy and I'll explain you clearly with step by step simple explanation. x = 2 sin ²2 theta Y= 2 cos²2 theta +1. X+y=2 sin ²2 theta +2 cos²2 theta + 1 = 2 (sin ²2 theta + cos²2 theta )+1 = 2(1) + 1(sin ²2Read more
