If `sintheta-costheta=1`,then find `sintheta.costheta`

if sintheta+costheta=3/2 then find sintheta.costheta

If sintheta+costheta=(7)/(5) , find sintheta.costheta .

If sintheta+costheta=(17)/(13) , then sintheta.costheta .

If 3sintheta+5costheta=3 , then 5sintheta-3costheta=?

If sintheta+costheta=(17)/(13) , then sintheta-costheta=?

If sintheta+costheta=x then sintheta-costheta=?

If (sintheta)/(x)=(costheta)/(y) then sintheta-costheta is equal to

If (1+ sintheta-costheta)/(1+ sintheta + costheta)+(1+sintheta+costheta)/(1+sintheta-costheta)= 4 , then which of the following values will be suitable for theta ?

If sintheta + 2 costheta=1 ,then prove that 2sintheta-costheta=2 .
