Question

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

Answer 1

Answer:

Step-by-step explanation:

(sin theta + 1 + cos theta) × (sin theta - 1 + cos theta) × sec theta cosec theta

[(sin theta + cos theta)²-1] × 1/cos theta sin theta

(sin (theta)² + 2sin theta cos theta + cos (theta)²-1) × 1/cos theta sin theta

(1+2sin theta cos theta -1) × 1/cos theta sin theta

sin 2 theta × 1/cos theta sin theta

2 sin theta cos theta × 1/cos theta sin theta
