> Note: Function and constant names are not case-sensitive. For example, Exp is the same as EXP or exp. The variable, which is the letter "x", is also not case-sensitive.
> Note: Text after proper mathematical expression will be ignored by the compiler. You can use this feature to comment your equation set.
> Note: In particular, you cannot use ^ for exponentiation, you must use the Power function instead.
> Note: All angle parameters and results of trigonometric functions are in radians. For degrees, multiply or divide by the Deg variable.
For example: Sin(30/Deg) will return 0.5, and ArcTan(1)*Deg will return 45.
> Note: All the algebraic, trigonometric, hyperbolic and transcendental routines map directly to Intel 80387 FPU floating point machine instructions.
> Note: The program is a graphing application and cannot be used as a scientific calculator. Though you can plot XY graph for floating-point values between 2.225E-308 (2-1022) and 1.797E+308 (21024), you cannot multiply two positive constants together with resulting values greater than 4096 (212). It is so designed. Use the "scientific calculator - ScienCalc" application instead.
> Note: As operands you can use numeric constants in any form (2, 2.0, 2e5, 2e-3) with decimal delimiter "period" or "comma", depending on your computer system configuration.
Example of formula: (2.0e-3*x) + square(x) + power(x;3) + power(2.55;4) + logbaseN(4;6.25)
Thus! If your computer system configuration uses "comma" as decimal delimiter/separator, 2.55 in the above example must be 2,55
Example of formula: (2,0e-3*x) + square(x) + power(x;3) + power(2,55;4) + logbaseN(4;6,25)
2. MaxX, minX: These are the limits of the drawing.3. Step: The smaller value it has, the more accurate drawing you get.
