If `sqrt((1-sinA)/(1+sinA))+sinA/cosA=1/cosA` for all permissible values of , then A can belong to

If sqrt((1-sinA)/(1+sinA))+(sinA)/(cosA)=(1)/(cosA), for all permissible values of A, then A belongs to

If sqrt((1-sinA)/(1+sinA))+(sinA)/(cosA)=(1)/(cosA), for all permissible values of A, then A belongs to (a) First Quadrant (b) Second Quadrant (c) Third Quadrant (d) Fourth Quadrant

cosA/(1−sinA) =

(1+sinA-cosA)/(1+sinA+cosA)=

Prove that sqrt((1+sinA)/(1-sinA))=(1+sinA)/cosA .

sinA/( 1+cosA) +sinA/(1−cosA) is equal to

((2sinA)(1+sinA))/(1+sinA+cosA) is equal to:

((2sinA)(1+sinA))/(1+sinA+cosA) is equal to:

(sinA)/(1+cosA)+(1+cosA)/sinA=2cosecA
