Solve `sqrt(3)costheta-3sintheta=4sin2thetacos3thetadot`

sqrt(3)costheta+sintheta=2

sqrt3costheta+sin theta=sqrt2

Express the following as a single trignometric ratio: sqrt3 costheta-sintheta sintheta-costheta .

sqrt(3)sintheta-costheta=sqrt(2)

Solve: costheta+sintheta=cost2theta+sin2theta

(sin3theta-cos3theta)/(sintheta+costheta)+1 =

costheta[{:(costheta,-sin theta),(sintheta,costheta):}]+sintheta[{:(sintheta,costheta),(-costheta,sintheta):}]=?

If 0^(@)ltthetalt90^(@) , then ((5costheta-4)/(3-5sintheta)-(3+5sintheta)/(4+5costheta)) is equal to

What is the simplified value of (2sin^(3)theta-sintheta)/(costheta-2cos^(3)theta) ?
