Plottron vs PyCalc

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.

What most people love first about PyCalc is that they can see and edit their entire calculation all at once. It's a simple idea but it makes a huge difference in the kinds of calculations people end up doing on mobile. But that just scratches the surface of PyCalc's features and capabilities. The more you learn, the more you'll see how easy it is to do calculations that were always too hard before on mobile. Jump in and learn a truly better way of calculating. Basic features: ● A new and better approach to mobile calculation ● A cleaner interface for complicated calculations than traditional calculators ● Calculate by voice ● A history list keeps track of your previous calculations ● Functions built in for a huge range of applications ● Multiple keyboards optimized for different use cases Advanced features: ● Based on the Python® language, with access to the power of a full Python 3.11.1 interpreter ● Programmable scientific calculator: An editable startup.py script allows you to define your own functions for easy access later ● Streamlined support for matrices and fractions ● Many standard Python packages, such as: math, statistics, random, sympy, mpmath, fractions, decimal and datetime ● Basic financial analysis functions: pv(), fv(), npv(), pmt(), etc. ● Built-in support for complex numbers ● Symbolic math via the sympy package ● http/https queries via requests package ● Much, much more...
