Question

Prove that cosec (360+theta) /sec(180-theta)*cos(360+theta) /cos(90+theta)=cotsqare theta

Answer 1

Answer:

=Cosec (360+theta)/sec (180+theta)*cos (360+theta)/cos(90+theta)

=cosec theta/-sec theta*cos theta/-sin theta

=cos theta/sin theta*cos theta/sin theta

=cos^2theta/sin^2theta

=cot^2theta (proved)
