Question

cos²0/sin0-cosec0 +sin0= 0​

Answer 1

LHS=

cos ^2 θ/sinθ −cosecθ+sinθ

= sinθcos 2 θ

= cos ^2 θ / sinθ - 1 /sinθ +sinθ

= 1-1/sinθ

=0

=RHS

Hence proved

Answer 2

Step-by-step explanation:

LHS = (cos^2 θ / sin θ) - cosec θ + sin θ

= (cos^2 θ / sin θ) - 1 / sin θ + sin θ

= cos^2 θ - 1 + sin^2 θ / sin θ

= 1 - 1 / sin θ

= 0 = RHS

Hence, proved.
