2. Copy and paste the following Sage code into the box:
t = var('t')
parametric_plot( [sqrt(2)*cos(t), sin(t) + (3/4)*sqrt(abs(cos(t)))],
[t,0,2*pi],aspect_ratio=1,fill=true,axes=false,
thickness=4, color='red',plot_points=2000,
fillcolor='pink'
)
3. Press Evaluate.
4. How can you hate that?
(I'm happy to acknowledge that the idea comes from
