Practice problem
Find all possible values of sin(x)\sin(x)sin(x) if xxx is a real number for which tan(2x)cos(x)=3.\frac{\tan(2x)}{\cos(x)} = 3.cos(x)tan(2x)=3.
13\frac{1}{3}31
−23-\frac{2}{3}−32
−1+196\frac{-1 + \sqrt{19}}{6}6−1+19
−1−196\frac{-1 - \sqrt{19}}{6}6−1−19
1+196\frac{1 + \sqrt{19}}{6}61+19
1−196\frac{1 - \sqrt{19}}{6}61−19
The described scenario is impossible.
Type a concept, like “slope” or “photosynthesis”.
