Step-by-step explanation:

LHS = cot a + tan a

= cos a / sin a + sin a / cos a

= cos² a + sin²a /sin a .cos a

= 1/sin a . cos a

=cosec a . sec a = RHS

Hence Proved ..

Answer 2

$\huge\boxed{Answer}$

Cot a + tan a

(1/tan a) + tan a

(1 + tan²a)/tana

Sec²a /tana

(1/Cos²a)/(Sina/Cosa)

Cosa /Sina*Cos²a

1/Sina*Cosa

2/2Sina*Cosa

2/Sin2a

2Cosec2a
