Step 1:  Find the \theta values by the trigonometric ratios of complementary angles


            NOTE: \tan \theta = \cot \theta

                        We know that   \cot \theta = \tan (90\degree - \theta) (Since    trigonometric ratios of complementary angles)

                        So, I can write equation as

                             \tan \theta = \tan(90\degree - \theta)

                            Therefore   \theta = 90\degree - \theta

                                            2\theta = 90\degree

                                               \theta = 45\degree


Step 2:  Find the value of the unknown trigonometric ratio ( \sec \theta)

              EXAMPLE:     \theta = 45\degree in the \sec \theta

                                    =   \sec 45\degree   

                                    = \sqrt{2}
