If `2sinalpha/(1+cosalpha+sinalpha)=y` then value of `(1-cosalpha+sinalpha)/(1+sinalpha)` is

If (2sinalpha)/(1+cosalpha +sinalpha)=y , then prove that (1-cosalpha+sinalpha )/(1+sinalpha) is also equal to y.

If (2sinalpha)/(1+cosalpha+sinalpha)=y , then prove that (1-cosalpha+sinalpha)/(1+sinalpha) is also equal to y.

If (2sinalpha)/(1+cosalpha +sinalpha)=y , then prove that (1-cosalpha+sinalpha )/(1+sinalpha) is also equal to y.

If (2sinalpha)/(1+cosalpha+sinalpha)=x then find (1-cosalpha+sinalpha)/(1+sinalpha)

If (2sinalpha)/({1+cosalpha+sinalpha})=y , then ({1-cosalpha+sinalpha})/(1+sinalpha) =

If (2sinalpha)/(1+cosalpha+sinalpha) =x, then (1-cosalpha+sinalpha)/(1+sinalpha) =

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) , then sinalpha+cosalpha and sinalpha-cosalpha is equal to

If sin.alpha/2+cos.alpha/2=1.4, then: sinalpha=

A square of side a lies above the x-axis and has one vertex at the origin. The side passing through the origin makes an angle alpha(0ltalphaltpi/ 4) with the positive direction of x-axis. equation its diagonal not passing through origin is (a) y(cosalpha+sinalpha)+x(sinalpha-cosalpha)="a (b) y(cosalpha+sinalpha)+x(sinalpha+cosalpha)=a (c) y(cosalpha+sinalpha)+x(cosalpha-sinalpha)=a (d) y(cosalpha-sinalpha)-x(sinalpha-cosalpha)=a
