(1+sintheta-costheta)2/(1+sintheta+costheta)=[1+sin2theta+2sintheta+cos2theta-2costheta(1+sintheta)]/[1+sin2theta+cos2theta+2sintheta+2costheta(1+sintheta)]=[2(1+sintheta)-2costheta(1+sintheta)]/[2(1+sintheta)+2costheta(1+sintheta)]=[2(1+sintheta)(1-costheta)]/[2(1+sintheta)(1+costheta)]= (1-costheta)/(1+costheta)
