SUMMARY
The equation sin²(x)tan(x) = 1356 can be rearranged to solve for the unknown angle x by following a systematic approach. First, substitute tan(x) with sin(x)/cos(x) and express cos(x) as √(1 - sin²(x)). This leads to a sixth-order polynomial after squaring both sides. By substituting y = sin²(x), the equation simplifies to a third-order polynomial, which can then be solved for y to ultimately find the values of x.
