Answer 1

Answer:

Hey mate here is your answer

Hope it helps.

Answer 2

Answer:

LHS = 1+cos@ -sin^2@/ sin@(1+cos@)

= 1-Sin^2@+ cos@/sin@(1+cos@)

= cos^2@+cos@/sin@(1+cos@) {1-sin^2@ = cos^2@}

take cos@ common in the numerator

=cos@(cos@+1)/sin@(cos@+1)

cos@+1 gets cancelled

=cos@/sin@

=Cot@ = RHS
