U7L3 Solve sin(x)sec(x)tan(x)/cot(pi/2-x)=1

In this example, we solve the trig equation by first applying a product identity and cofunction identity, setting the quadratic equation equal to zero, factoring the quadratic binomial, and using the zero product property to set each factor equal to zero to solve for x. We finish by using a graphing calculator to check the solutions.
