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}
