[" 11.Show that the equation to the normal to "],[qquad x^(2/3)+y^(2/3)=a^(2/3)]

Show that the equation of the normal to x^(2/3) + y^(2/3) = a^(2/3) is y cos theta - x sin theta = a cos 2"theta" where theta is the inclination of the normal to x-axis.

Prove that the equation of the normal to x^((2)/(3))+y^((2)/(3))=a^((2)/(3)) is y cos theta-x sin theta=a cos2 theta where theta is the angle which the normal makes with the axis of x.
