Question 20

The curve C C\,C has parametric equations

x=t2−4x = t^2 - 4x=t2−4, y=t3−4ty = t^3 - 4ty=t3−4t, t∈Rt \in \mathbb{R}t∈R

a.

Show that C C\,C crosses itself at the origin, and state the two values of t t\,t for which C C\,C passes through the origin.

[4]
b.

Find an equation of the tangent to C C\,C at the point where t=2t = 2t=2.

[3]
c.

Hence write down an equation of the other tangent to C C\,C at the origin.
