$\large \bigstar \: \bf \red{Question :-}$

◆ Prove the Identity :-

$\sf{tan \: A \: + \: cot \: A \: = \: sec \: A \: + \: cosec \: A}$
​

Answer 1

Step-by-step explanation:

tan A + cot A = 1 ÷ cotA + cot A = 1+ cot^2A ÷cotA =cosec^2A ÷ cotA = 1 ÷ sin^2A × sinA ÷ cos A = 1 ÷ sinA cosA = cosecA. secA. Hence proved
