यदि `tantheta=(sinalpha+cosalpha)/(sinalpha+cosalpha)` है तो `sinalpha+cosalpha` का मान क्या होगा?

costheta-sintheta=cosalpha-sinalpha

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

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 sinalpha+cosalphaandsinalpha-cosalpha are equal to

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 A=[(cas alpha, sinalpha),(-sinalpha,cosalpha)], AA'=

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