Question
Evaluate the following:
$\text{cosec 31}^\circ-\sec59^\circ$

Answer

We have to find: $\text{cosec 31}^\circ-\sec59^\circ$$$Since $\text{cosec}(90^\circ-\theta)=\sec\theta$
So, $=\text{cosec 31}^\circ-\sec59^\circ$ $=\text{cosec}(90^\circ-59^\circ)-\sec59^\circ$ $\sec59^\circ-\sec59^\circ$ $= 0$So value of $=\text{cosec 31}^\circ-\sec59^\circ\text{ is 0}$
