Question

prove that 1 + cot square A upon 1 + cosec A is equals to cosec a​

Answer 1

Answer:

1 + Cot²A / CosecA

using identity Cosec²θ - Cot²θ = 1 => 1 + Cot²θ = Cosec²θ

= Cosec²A / CosecA

= CosecA

= R.H.S

Hence proved

Answer 2

Answer:

Sorry I can't use the alpha sign using A instead.

Step-by-step explanation:

1 + (Cot²A / 1+CosecA)

using identity Cosec²A - Cot²A = 1

= 1 -1 +cosec^2A+cosecA/1+cosecA

=cosec^2A+cosecA/1+cosecA

=CosecA(1+cosecA)/(1+cosecA)

=CosecA

Hence proved
