Answer 2

/* There is a mistake in the last term .

It may be like this */

$\red{ Value \:of \: \frac{sec 17\degree}{Cosec 73 \degree } + \frac{tan 68\degree}{Cot 22 \degree } + \frac{cos^{2} 44\degree}{Sin^{2}46 \degree } }$

$= \frac{sec (90- 73\degree)}{Cosec 73 \degree } + \frac{tan (90-22\degree)}{Cot 22 \degree } + \frac{cos^{2} (90-46\degree)}{sin^{2}46 \degree }$

$= \frac{cosec 73\degree}{Cosec 73 \degree } + \frac{cot 22\degree}{Cot 22 \degree } + \frac{sin^{2} 46\degree}{sin^{2}46 \degree }$

$= 1 + 1 + 1 \\= 3$

Therefore.,

$\red{ Value \:of \: \frac{sec 17\degree}{Cosec 73 \degree } + \frac{tan 68\degree}{Cot 22 \degree } + \frac{cos^{2} 44\degree}{Sin^{2}46 \degree } }\green {= 3}$
