Let's substitute
Quadratic equation in u.
Factor the quadratic equation.
First factor:
2 solutions for this equation.
x=340.53 degrees and x=199.47 degrees
Second factor:
sin(x) is never greater than 1, so there are no additional solutions.
Below is the graph of the function.
Note : x axis is measured in radians.
360 degrees = 6.28 radians
340.53 degrees = 5.94 radians
199.47 degrees = 3.48 radians
