If x and y are connected parametrically by the equations given, without eliminating the parameter, Find `(dy)/(dx)`.
`x=costheta-cos2theta, y=sintheta-sin2theta`

Text Solution

Verified by Experts

`(deltay)/(deltatheta)=costheta-2cos2theta`
`(deltax)/(deltatheta)=sintheta+2sintheta`
`(deltay)/(deltax)=(costheta-2cos2theta)/(-sintheta+2sin2theta)`
