Equation Examples

Cartesian (y=f(x))
  • y = x^2 + 3*x - 5
  • y = sin(x) * exp(-x/10)
  • y = sqrt(x^2 + 1)
Polar (r=f(θ))
  • r = 2 + 3*cos(5*θ)
  • r = θ/2 (Spiral)
  • r = 1 + sin(θ) (Cardioid)
Parametric
  • x = t*cos(t), y = t*sin(t) (Spiral)
  • x = 3*cos(t), y = 2*sin(t) (Ellipse)
  • x = t - sin(t), y = 1 - cos(t) (Cycloid)
With Variables
  • y = a*x^2 + b*x + c
  • y = A*sin(k*x + φ)
  • r = a + b*cos(n*θ)

Troubleshooting

Graph Not Displaying
  • Blank canvas:
    • Check if equation syntax is correct
    • Verify the equation is visible in the equations list
    • Try zooming/resetting view (Ctrl+0)
  • Partial graph:
    • Check if function is defined in the viewing window
    • Adjust the x/y range in settings
    • For discontinuous functions, try smaller steps
Equation Errors
  • "Invalid equation" message:
    • Check for unmatched parentheses
    • Verify multiplication signs are explicit (use * instead of implied)
    • Replace special characters with standard operators
  • Unexpected results:
    • Check angle mode (radians/degrees)
    • Verify variable values in the settings panel
    • Test with simpler equations first
Performance Issues
  • Slow rendering:
    • Reduce number of simultaneous equations
    • Simplify complex equations
    • Close other browser tabs
  • Laggy interaction:
    • Disable animations in settings
    • Reduce grid density
    • Use simpler line styles
