If `2costheta+5sintheta=4`, then `5costheta-2sintheta=?`

If 3costheta=5sintheta , then ((5sintheta-2sec^(3)theta+2costheta)/(5sintheta+2sec^(3)theta-2costheta))=?

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

If sintheta+costheta=sqrt(2)sintheta , then sintheta-costheta=?

If costheta+sintheta=sqrt(2)costheta , then costheta-sintheta is

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

If sintheta+costheta=sqrt2costhetathen costheta-sintheta is equal to

Eliminate theta in the following (i) 2sintheta=x, 3costheta=y (ii) costheta + sintheta=x, costheta-sintheta=y

costheta[[costheta, sintheta], [-sintheta, costheta]]+sintheta[[sintheta, -costheta], [costheta, sintheta]]=

If 3 cot theta =4, " write the value of " ((2costheta+ sintheta ))/((4costheta- sintheta)).

If 5tantheta=4 , then (5sintheta-3costheta)/(5sintheta+2costheta) is equal to
