Learn to solve your trigonometric equation with sine squared

The video tutorial demonstrates how to solve the trigonometric equation 4/4 sine squared of X = 1. The instructor begins by isolating the variable X and simplifying the equation using division and square roots. The unit circle is then used to find specific angle solutions where sine of X equals 1/2. The tutorial concludes by explaining how to find all possible solutions by considering coterminal angles and adding multiples of 2π.
