Question

prove : ( 1 - cos theta + sin theta ) ( 1 + cos theta + sin thata) = 2 sin theta ( 1 + sin theta )​

Answer 1

Answer:

Answer:

Sin theta/1+cos theta +1+cos theta/sin theta = 2 cosec theta is proved

Solution:

Proof: In the left hand side of the equation it is given that

  [Taking L.C.M of sinθ and 1+cosθ]

     

   

   [Taking 2 common]

= 2cosecθ = Right Hand Side of the equation.

Thus Sin theta/1+cos theta +1+cos theta/sin theta = 2 cosec theta is proved
