Question

(cosecA-cotA)sq=1-cosA/1+cosA​

Answer 1

$\huge\underbrace {\bf{✯AnSweR:}}$

$\boxed {\red{(cosecA−cotA)²= {\frac {1}{sinA}−\frac {cosA}{(sinA)²}}}}$

➝ $\Large {\frac {(1−cosA)²}{(sinA)²}}$

➝ $\Large {\frac {(1−cosA)²}{(1−cos²A)}}$

➝ $\Large {\frac {(1−cosA)²}{(1−cosA)(1+cosA)}}$

➝ $\Large {\frac {(1−cosA)}{(1+cosA)}}$

☞ LHS = RHS
