Question

Which of the following is correct for some $\theta$, such that $0^{\circ }$ $\le \theta <$ ${90}^{\circ }$

• A. $\frac{1}{sec\theta }$ > 1
• B. $\frac{1}{sec\theta }$ < 1
• C. $sec\theta$ = 0
• D. $\frac{1}{cos\theta }$ < 1

Answer 1

The correct option is B

$\frac{1}{sec\theta }$ < 1

$\frac{1}{sec\theta }$ = cos $\theta$. And value of cos $\theta$ ranges from 0 to 1
