Plottron vs Command-Line Calculator Usage & Stats
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.

Command-Line Calculator (CLCalculator) provides the most fluid interface, especially if you are performing chained calculations i.e. multiple calculations that rely on the results of previous calculations.
By providing a command-line interface, CLCalculator allows you to easily enter and view the history of your calculations. You focus on your calculations instead of being intimidated by myriad of buttons on a traditional calculator interface! In addition to performing basic calculations, CLCalculator provides an array of features such as:
- Assign and reuse variables
- Complex numbers
- Number bases i.e. binary, octal, hexadecimal
- Constants e.g. e, pi
- String manipulation
- Matrices
- Unit conversion: in-built and user-defined (create your own units!)
- Functions: in-built and user-defined (create your own functions!)
- Arithmetic functions e.g. fraction, square root, rounding off, ceiling, floor, logarithm
- Algebra functions e.g. derivative, simplify symbolic expressions, solve linear equations
- Bitwise functions e.g. bitwise and, not, or, left and right shift
- Combinatorics functions e.g. Bell, Catalan, Stirling numbers
- Geometry functions
- Logical functions e.g. and, not, or, xor
- Probability functions e.g. combinations, permutations, factorial
- Relational functions
- Set functions e.g. cartesian product, intersection, union
- Statistics functions e.g. mean, median, mode, standard deviation, variance
- Trigonometry functions e.g. sin, cos, tan, cot, sinh, acos
- and much more!
The app also comes with a comprehensive in-built help system with plenty of examples. CLCalculator is powered by math.js (https://mathjs.org/)
