4. Curve of cardioid You should have learned cardioid in high school. The equation is like below: Polar equation: r = a (1 + Cos 0) Cartesian equation (x² + y² + ax)² = a² (x² + y²) Some websites show the curves like below: BODO Figure 3. 6.3 -9.5 -1 -6.9 r-a + bcose (a) r-a-bcose (b) C P.. r-absine (c) r-a-bsine (d) Write a computer program (with graphic part and GUI part) that draws cardioid similar to what you see in Figure 3 (in Figure 3, we see two parameters a and b, while the equations I found above only have a parameter a; you can use either way). Have a GUI part so that the user can change parameter a (and b if appropriate) and color of the cardioid as needed.

Transcribed Image Text:4. Curve of cardioid
You should have learned cardioid in high school. The equation is like below:
Polar equation:
r = a (1 + Cos 0)
Cartesian equation
(x² + y² + ax)² = a² (x² + y²)
Some websites show the curves like below:
BO POLO 6
r-a-bcos
(b)
r-a-bsine
(d)
Figure 3.
r-a + bcos
r-a+bsine
Write a computer program (with graphic part and GUI part) that draws cardioid similar to what you see in
Figure 3 (in Figure 3, we see two parameters a and b, while the equations I found above only have a parameter
a; you can use either way). Have a GUI part so that the user can change parameter a (and b if appropriate) and
color of the cardioid as needed.
