Answer 1

Answer:

Hope you understand the answer

Answer 2

Step-by-step explanation:

sin ^2 theta/cos theta - sec theta + Cos theta

=(sin theta/cos theta)sin theta -(1/cos theta) + Cos theta

=(tan theta)(sin theta)+(-1+cos^2theta)/cos theta

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

=1-(tan theta)(sin theta)

=1-1

=0
