Question

prove that 1+cos tita /sin tita -sin tita /1+cos tita =2cot tita​

Answer 1

Step-by-step explanation:

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

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

=sin@/(1-cos@)

putting value in question

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

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

=sin@(2cos@)/sin^2@

=2cos@/sin@=2cot@
