Equation of the line passing through the point `(acos^3theta, a sin^3theta)` and perpendicular to the line `xsectheta + y cosec theta =a` is `xcostheta-ysintheta =asin2theta`.

`x cos theta + y sin theta = 2 a cos 2 theta`

`x sin theta -y cos theta = 2a sin 2 theta `

`x sin theta + y cos theta = 2a cos theta `

none of these
