Math in One graphing calculator can evaluate any mathematical expression of any length and complexity that includes real or complex numbers. It can operate in decimal or common fractions format. It graphs in Cartesian, polar coordinates or parametric equations. Expressions can be entered in editor text box Input Output Display (IOD) and then edited in the middle of the string (text) on any line. The calculation execution can be performed from any line in (IOD). If a user makes an unsupported entry during the operation of this software, the calculator will generate an error message and explanation. The help is built in to the calculator (Alt 0 - cm, help) and available on line. It also includes a uniquely designed Unit Converter, Financial Analysis (savings, loans, bonds) and can save Graphs, Memory, Expressions and IOD in to a File.
In Cartesian coordinates, plotted multiple graphs can be moved and resized. Function values may be displayed for a specific independent variable. Tracing the pointers on a screen, one can find zeros, minimums, maximums and intersections of functions. Function’s first and second order derivative can be added to the graph display. Draw tangent or perpendicular line to the existing function at select point or line crossing two points on one or two functions. Calculate intersection of two functions and area bounded by one, two or three functions.
The Unit Converter has 19 different categories of units of measurement. There are 20 SI prefixes that can be applied to any unit. It supports 170 unique units, 1990 derived units, and when the prefixes are included there is a combination of 43,200 different units that can be converted. Any number in calculator’s IOD can be moved to UC, converted and then replaced. In addition, the number to be converted can be edited anytime directly in UC.
It recognizes 16 operators, over 60+ basic functions that are calculated in complex numbers, and 85 mathematical and physical constants(e.g. “trigonometric, hyperbolic, logarithmic functions and there invers”, “probability functions” "beta function", "gamma function", "error functions", and more special functions, " logical operators like exclusive or (XOR)", "Planck's constant", "atomic mass constant", "Avogadro's number",...). Finds zeros of any function in real or complex domain. Evaluates derivatives up to nine order and calculates integrals. Function’s first and second order derivative and Integral can be used in expression.
Evaluates calculation error for any function or expression. Displays calculation results in selected Sig Fig notation. Converts between binary, octal, decimal, and hexadecimal number systems. Performs arithmetic and logical operations on any number systems ("and", "or", "exclusive or", "not", "shift"). Executes trigonometric function calculations in radians, degrees, or gradients. The value of the last calculation computed is automatically stored in an "arg" variable, which is then ready for use in the next operation. Results from any calculation can be stored in the memory entry for future use with no limitation on the number of memories. Contains additional memory known as “Expressions” to store mathematical formulas that can be used in applications and graphing functions.
