Graphulator With Calculus vs Plottron

Graphulator is a numerical graphing calculator for 2 or 3 variable equations. Plot both functions and non-functions. Includes data output! Now includes numerical calculus. Scientific calculator. Trigonometry. Logarithms. Absolute values. Scientific notation. Basic Calculator. Function calculator. Two variable calculator. Three variable calculator. Numerical analysis. Drag grid or use controls to move or change the scale. Drag three variable grid to rotate. Graphulator can miss non-functions 1/50 the grid scale. The user can adjust the accuracy or change the grid scale including adjusting the width and height independently. Changing the accuracy requires upgrade. Graphulator boasts being the only calculator which can perform calculus on non-functions numerically (equations which cannot be reduced to a function). It should be noted that these derivatives differ from standard calculus. Graphulator boasts being the only numerical calculator which can plot three variable non-functions. (Equations of the form f(xyz) = f(xyz)). If you believe either of these claims to be untrue, let us know (contact@Graphulator.com).

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 • Probability density functions: Binomial, Normal (Gaussian), Student’s t • Cumulative probability density functions • Inverse CDF functions: Normal (Gaussian), Student’s t 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) Complex magnitude plot in 3D Regular mode: abs(1/cos(X+Yi)) Notes: • Swipe left for settings. • Use semicolon (;) to separate functions in parametric relations. • Swipe down on keypad to show full history.
