cos^2(2x)-2sin^2(x)-1=0

cos^{2} (2 x) - 2 sin^{2} (x) - 1 = 0

cos^2(x)+2=sin(x)

cos^{2} (x) + 2 = sin (x)

-sin(2x)-3cos(x)=0

- sin (2 x) - 3 cos (x) = 0

solvefor x,y=3cos(fxx+pi/2)+5

so l v e f or x, y = 3 cos (f xx + \frac{π}{2}) + 5

sin(x)cos(x)=sin(x),0<x<= 2pi

sin (x) cos (x) = sin (x), 0 < x \leq 2 π
