Question

prove that 1/cos²theta + (2sin theta) /cos theta = (1+tan theta)²

Answer 1

answer of this question

Answer 2

Answer:

Step-by-step explanation:

=1/cossqare2 theta +2sintheta

=1/costheta+2sintheta.costheta/cos sqare2 theta

=1+2sintheta.cos theta /cossquare theta                 weknown sinsqaure theta +cos sqaure =1

so (a+b)=a2+b2 +2ab

=(sintheta +cos theta /costheta)2

=(1+tantheta)2
