Find the equation of a line which passes through (2 \cos ^{3}(\\theta), 2 \sin ^{3}(\\theta)) and is perpendicular to the line x \cos (\\theta)-y \sin (\\theta)=2 \cos (2 \\theta).

Correct Answer is : xsec(θ)+ycosec(θ)=2

x \sec (\\theta)+y {\cosec}(\\theta)=2

x {\cosec}(\\theta)+y \sec (\\theta)=2

x \sin (\\theta)+y \cos (\\theta)=2

x \cos (\\theta)+y \sin (\\theta)=2
