Question

prove that (cosecθ+cotθ-1)/(cotθ-cosecθ+1)= sinθ/1-cosθ

Answer 1

we know that cosec^2-cot^2=1

so we can write

(cosec+cot-(cosec^2-cot^2)/(cot-cosec-1)(

by taking cosec +cot common

(cosec+cot)(1-(cosec-cot)/(cot-cosec+1)

=(cosec+cot)

=sin/1-cos

wait i will send a pic
m solving in notebook
wait plz

Answer 2

answer is

$sin \div 1 - \cos$
