Answer 2

Step-by-step explanation:

LHS

(Sin Theta+Cosec theta)^2+(cos theta+sec theta) ^2

Sin^2theta+cosec^2theta+2sin theta cosec theta+cos^2theta +sec^2theta+2cos theta sec theta

(Sin^2 theta+cos^2 theta) +cosec^2 theta+sec^2+2 sin theta*1/sin theta+2cos theta*1/cos theta

1+cosec^2 theta+sec^2+2+2

5+1+cot^2theta+1+tan^2theta

7+cot^2theta+tan^2theta
