If `t a ntheta=(sinalpha-cosalpha)/(sinalpha+cosalpha)` , then show that `sinalpha+cosalpha=sqrt(2)costheta`

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) then show that sinalpha+cosalpha=sqrt(2)costheta .

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) then show that sinalpha+cosalpha=sqrt(2)costheta .

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) then show that sinalpha+cosalpha=sqrt(2)costheta .

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) , then show that sinalpha+cosalpha=sqrt(2)costheta .

if tan theta=(sinalpha-cosalpha)/(sinalpha+cosalpha) show that, sin alpha+cosalpha=pmsqrt(2)cos theta

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

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) then prove that sqrt2(costheta) =cosalpha+sinalpha

If tantheta=(sinalpha-cosalpha)/(sinalpha+cosalpha) , then sinalpha+cosalphaandsinalpha-cosalpha are equal to

If A_(alpha)=[(cosalpha,-sinalpha),(sinalpha,cosalpha)] , then

IF A=[{:(cosalpha,sinalpha),(-sinalpha,cosalpha):}] , then show that AA'=A'A
