Plottron 1.7.8

A graphing + scientific calculator.

• 2D and 3D graphing
  • Graphs regular functions, parametric relations, and functions in polar/spherical coordinates.
  • Implicit graphing
  • Visualization of complex maps w=f(z) featuring domain coloring plots
  • For 2D functions: Info mode with tangent line and 2nd-order Taylor approximation
• Scientific calculator features:
  • User-defined variables and functions
  • Symbolic derivative (e.g.: D(x, sin(x))
  • nCr, nPr, factorial
  • Complex numbers
  • Live evaluation (calculate as you type)
  • Calculation history
• Examples:
  • Implicit graph: cos(X)=sin(Y)
  • Graph a parabola in Regular mode: X^2
  • Graph a circle in Parametric mode: cos(T);sin(T)
  • Set a variable: X=5
  • Use a variable: X+4: 9
  • Define a function: f(X)=X+1
  • Use a defined function: f(2): 3
  • Symbolic derivative: D(X,sin(X)): cos(X)
• Notes:
  • Swipe left for settings.
  • Use semicolon (;) to separate functions in parametric relations.
