The video tutorial explains how to solve a trigonometric equation involving cosecant and secant functions. It begins by moving variables to one side and factoring the equation. The tutorial then discusses why the cosecant of X equals zero has no solution and proceeds to solve the secant of X equals 2. The instructor identifies angles where cosine of X equals 1/2 and finds all solutions using coterminal angles.
