Graph the curve represented by the following pair of parametric equations:
x = 2 cos3(t), y = 2 sin3(t)
This curve is called a hypocycloid of four cusps.
- Prepare the program for graphics.
- If the first menu item is Algebra then press .
- Press for Author.
- Enter the function
[2(cos t)^3,2(sin t)^3]
- Press twice and then to get the graph.
