??? Introducing Scientific Calculator 3D Free ???

Description:

"Scientific Calculator 3D Free" is a powerful math tool for Android consists of 5 calculators. "Matrix Calculator", a tool to calculate the decompositions and various operations on matrix, "Equation Solver" an instrument capable of solving equations of degree n, "Graphing Calculator" a real scientific graphing calculator can draw graphs in 2D and 3D, "Currency Converter" a currency converter always updated with the new exchange rates and "Unit Converter" a small units converter. In addition we find a comfortable Periodic Table of Elements.

Value converter in binary, octal or hexadecimal input prefixing respectively 0b, 0o, 0x, in decimal.
binary: 0b1010
octal: 0o17
hexa: 0x100

--Derivative
It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function, and must be followed by open-parentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function.
Eg f (x) = x ^ 2 + x, after insertion, type f '(x) to display the graph of the derivative.

--Multi plot

To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";".
