The equation also has "hint: Use the Pythagorean identity to replace in the given equation" I tried to factor and simplify but I got an incorrect answer
"to replace sin² Ɵ"
cos=sqrrt(1-sin^2) sin2+sqrt(1-sin^2)=2, let sin^2 be x x+sqrrt(1-x)=2 x-2=sqrrt(1-x) square both sides x^2-4x+4=1-x x^2-3x+3=0 (x-1)(x-3)=0 x=1 x=3 remember sin^2 is x so find that
sin² Ɵ = 1 sin² Ɵ = 3 sin Ɵ = 1 sin Ɵ = sqrt(3) Ɵ = 90 degrees undefined or pi/2 radians
@pasta is that correct
