Question

Plz provide me the answer as Early as possible And plz provide answer.​

Answer 1

Answer:

1+sin@+cos@/1-sin@+cos@

=(1+(sin@+cos@))^2/(1+cos@)^2-sin^2@(multiply numerator and denominator by 1+sin@+cos@

=1+sin^2@+cos^2@+2sin@+2sin@cos@+2cos@/1+cos^2@+2cos@-sin^2@

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

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

=1+sin@/cos@
