If the normal to the curve x^((2)/(3))+y^((2)/(3))=a^((2)/(3)) makes an angle phi with the x-axis,show that its equation is,y cos phi-x cos phi=a cos2 phi

If the normal to the curve x^((2)/(3))+y^((2)/(3))=a^((2)/(3)) at any point makes an angle phi with posititive direction of the x-axix, prove that, the equastion of the normal is y cos phi- x sin phi= a cos 2 phi

If a normal of curve x^(2//3)+y^(2//3)=a^(2//3) makes an angle phi from X-axis then show that its equation is y cos phi -x sin phi = a cos 2phi .
