Question

What is the relation between $sec\theta$ and $tan\theta$ for any value of $\theta$?

• A. $ta{n}^2\theta +se{c}^2\theta =1$
• B. $se{c}^2\theta +1=ta{n}^2\theta$
• C. $ta{n}^2\theta +1=se{c}^2\theta$
• D. None of these

Answer 1

The correct option is C $ta{n}^2\theta +1=se{c}^2\theta$

The trigonometric identity between $sec\theta$ and $tan\theta$ is $ta{n}^2\theta +1=se{c}^2\theta$.
