Question

prove that (1 + sinθ − cosθ /1 + sinθ + cosθ )+ (1 + sinθ + cosθ/ 1 + sinθ − cosθ) = 2cosecθ please give me answer fast

Answer 1

Step-by-step explanation:

{(1+sintheta-costheta)2+(1+sintheta+costheta)2}/{(1+sintheta)2-costheta2

={4(1+sintheta)}/2sintheta(1+sintheta)

=2cosectheta

[acc to trigonometry,

sintheta2+costheta2=1]
