Question 4

A curve C C\,C has the parametric equations

x=sin⁡2tx = \sin^2 tx=sin2t, y=sin⁡2ty = \sin 2ty=sin2t, where 0<t<π0 < t < \pi0<t<π

a.

Show that a Cartesian equation for C C\,C is

y2=4x(1−x)y^2 = 4x(1 - x)y2=4x(1−x)

[4]
b.

State the set of values of x x\,x for which C C\,C is defined, and describe C C\,C geometrically.
