Description
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 2ndorder Taylor approximation
Scientific calculator features:
Userdefined 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.
