5 0

Answer:

\sec\theta=\sqrt{1+\tan^2\theta}

Step-by-step explanation:

The trigonometric identity is :

\sec^2\theta-\tan^2\theta=1\\\\or\\\\\sec^2\theta=1+\tan^2\theta

We need to express secθ in terms of tanθ.

The above equation becomes,

\sec\theta=\sqrt{1+\tan^2\theta}

Hence, this is the required solution.
