Question

prove that:-
cosecA + 1 ÷ cosecA - 1 = sec A + tan A​

Answer 1

Step-by-step explanation:

( cosecA +1)/(cosec A - 1) = (secA+tanA)^2

L.H.S.

=( 1/sinA +1)/( 1/sinA - 1)

=(1+sinA) /(1-sinA).

=(1+sinA)×(1+sinA)/(1-sinA)×(1+sinA)

=(1+sinA)^2/(1-sin^2A)

=(1+sinA)^2/cos^2A.

=(1/cosA+sinA/cosA)^2

=(secA+tanA)^2 ,proved.
