If `asinphi+bcosphi=c` then `acosphi-bsinphi` is

If cos theta =(a cos phi+b)/(a+bcosphi) then ("tan"(theta)/2)/("tan"(phi)/2)=

If costheta=((acosphi+b))/((a+bcosphi)) , then the value of tan (theta//2) is equal to

If costheta=(acosphi+b)/(a+bcosphi) . Show that : tan.(theta)/(2)=pmsqrt((a-b)/(a+b))tan.(phi)/(2).

If cos theta=(acosphi+b)/(a+bcosphi)(theta,phiacute angle) show that tan(theta/2)=sqrt((a-b)/(a+b))tan (phi/2)(a>b)

If acosphi=b costheta ,show that a tantheta+b tanphi=(a+b)tan((theta+phi)/2)
