Question

Show that the equation of normal at any point t on the curve x=3cost-cos^3t and y=3sint-sin^3t is 4 (y cos^3t- xsin^3t)=3sin 4t.

Answer 1

Step-by-step explanation:

Show that the normal at any point o to the curve

x = a coso + a 0 sin 0, y = a sino - a0 cose

is at a constant distance from the origin.hy
