`(1)/(1+sintheta)+(1)/(1-sintheta)` is equal to __________.

((1+sintheta))/((1-sintheta))=?

sqrt((1+sintheta)/(1-sintheta)) = __.

sqrt((1+sintheta)/(1-sintheta))+sqrt((1-sintheta)/(1+sintheta)) is equal to

If pi/2ltthetaltpi , then sqrt((1-sintheta)/(1+sintheta))+sqrt((1+sintheta)/(1-sintheta)) is equal to a. 2 sectheta b. -2sectheta c. sectheta d. -sectheta

If x=(2sintheta)/(1+costheta+sintheta) , then prove that (1-costheta+sintheta)/(1+sintheta) is equal to x .

If x = (2sintheta)/(1+costheta+sintheta), then (1-costheta+sintheta)/(1+sintheta) is equal to

If x=(2sintheta)/(1+costheta+sintheta),t h e n(1-costheta+sintheta)/(1+sintheta) is equal to

If 0lt thetalt(pi)/(2')and if(y+1)/(1-y)=sqrt((1+sintheta)/(1-sintheta')) they y is equal to
