A Java-based application to visualize mathematical curves in Cartesian and Polar (Radial) coordinate systems. The app uses sliders for real-time control over parameters like Amplitude (A), Frequency (W), and Phase Shift (PHI).
| Curve Name | Graph Preview | Formula Used |
|---|---|---|
| Sine Wave (Blue) |  |
Math.sin(W * x + PHI) * A |
| Cosine Wave (Magenta) | |
Math.cos(W * x + PHI) * A |
| Tangent Wave |  |
Math.tan(W * x + PHI) * A * 0.1 |
| Triangle Wave |  |
2 * A / π * asin(sin(W * x + PHI)) |
| Damped Sine |  |
sin(W * x + PHI) * exp(-0.01 * x) * A |
| Pulse Train |  |
(sin(W * x + PHI) > 0 ? 1 : 0) * A |
| Harmonic Blend |  |
(sin(W * x + PHI) + sin(3W * x + PHI)) / 2 * A |
| Sine of Sine |  |
sin(W * x + PHI) * sin(0.8W * x + PHI) * A |
| Curve Name | Graph Preview | Formula (r = ...) |
|---|---|---|
| Cardiod |  |

|---|---|---|
| Lissajous Curve |  |
x = A·sin(W·t + φ) y = A·sin(2·W·t) |
| Parametric Archimedean Spiral |  |
x = (t/30)·cos(W·t) y = (t/30)·sin(W·t) |
| Hypotrochoid |  |
x = (A - 20)·cos(W·t) + 40·cos(((A - 20)/20)·W·t) y = (A - 20)·sin(W·t) - 40·sin(((A - 20)/20)·W·t) |
| Helix (3D) |  |
x = A·cos(W·t) y = A·sin(W·t) z = t |
- c = x + iy (a point in the complex plane)
- z₀ = 0
- Recurrence: zₙ₊₁ = zₙ² + c

The app provides interactive sliders to dynamically update curves:
int function(float x){
A = sliderA.getValue();
W = sliderW.getValue()/1000.0;
PHI = sliderPHI.getValue()/100.0;
return (int)(Math.sin(W * x + PHI) * A); // Sine Wave
}
public AppCartesian(){
points = new ArrayList<>();
new Timer(sliderDelay.getValue(), e -> {
x += (float)(sliderStep.getValue()/10f);
add -> points.add(new Point((int)x,function(x),(int)size,Color.BLUE));
repaint();
}).start();
}
