Plottron vs Mathgra Math Grapher

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) 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. Tap on answer to show keypad again.
