Question

If cos theta=1/2, then the value of (cos theta-sec theta) is?​

Answer 1

$\huge{\textbf{{\color{navy}{Ans}}{\purple{we}}{\pink{r}}{\color{pink}{♡\:}}}}$

${\underline{\boxed{{\rm{ \cos( \theta) = \frac{1}{2} }}}}}$

$\cos( \theta) = \frac{1}{ \sec( \theta) }$

This means ,

$\color{red} \: {\underline{\boxed{{\rm{ \sec( \theta) = 2}}}}}$

Now , we have to find the value of

$\cos( \theta) - \sec(\theta)$

$\frac{1}{2} - 2$

$\frac{1 - 4}{2} = \frac{ - 3}{2}$

Hope this helps you to resolve your problem !!
