To solve for x, we can first rewrite the equation using the cosine double angle identity:
3sinx*cosx = sin2x
Now our equation becomes:
sin2x + cos^2x = 0
Using the Pythagorean identity sin^2x + cos^2x = 1, we can substitute sin^2x = 1 - cos^2x into the equation:
1 - cos^2x + cos^2x = 01 = 0
This equation has no solution, which means the original equation 1-3sinx*cosx+cos^2x=0 also has no solution.
