                     sec%5E2%28theta%29%22%22=%22%22%282tan%28theta%29%29%2F%28sin%282theta%29%29

Work with the right side only:

Use an identity for the numerator and denominator

                            %282%2A%28sin%28theta%29%2Fcos%28theta%29%29%29%2F%282sin%28theta%29cos%28theta%29%29 

                            %282sin%28theta%29%2Fcos%28theta%29%29%2A%281%2F%282sin%28theta%29cos%28theta%29%29%29

                            

                            1%2F%28cos%28theta%29%2Acos%28theta%29%29

                            1%2Fcos%5E2%28theta%29

                            sec%5E2%28theta%29
