Well let's see.

The equation has exactly one solution.
Hope this helps.
4 6/9= 38/9
7 5/3= 26/3
3 7/8= 31/8
5 19/14 =89/14



→ Substitute cos 2x and sin 2x by their expressions

→ Subtract both sides by sin x

→ Take sin x as a common factor in the right side

From the graph, the equation has 4 solutions, the intersection points between the 2 graphs
