Practice problem
Find all possible values of sin(x)\sin(x)sin(x) if 4cos2x=2sin2x−1.4\cos^2x=2\sin^2x-1.4cos2x=2sin2x−1.
56\frac{\sqrt{5}}{6}65
−56-\frac{\sqrt{5}}{6}−65
56\sqrt{\frac{5}{6}}65
−56-\sqrt{\frac{5}{6}}−65
The described scenario is impossible.
Type a concept, like “slope” or “photosynthesis”.
