$\large\boxed{\fcolorbox{blue}{yellow} {Additional Information }}$

There are some trigonometric identities.

They are very basic for the study of Trigonometry.

They are as

$1) \: {sin}^{2} \alpha + {cos}^{2} \alpha = 1 \\ \\ 2) \: {sec}^{2} \alpha = 1 + {tan}^{2} \alpha \\ \\ 3) \: {cosec}^{2} \alpha = 1 + {cot}^{2} \alpha$

Hope it helps!
