V-Solve is a programmable scientific calculator for iPhone and iPad that is designed to solve real problems in engineering and science.

(V-Solve has all of the features of V-Graph Save, except for graphing and the ability to save equations to the library. V-Solve has a demo feature which shows the graphing features of V-Graph Save for a select set of equations.)

Overview of Features

• Solves explicit and implicit equations.

• Equations are entered and displayed in their natural form, as they would appear in a textbook.

• 59 categories of units in library, divided into english, metric, and SI systems.

• Constants and user-defined unit conversions can be saved into libraries.

• Well-organized Main, Trigonometric, English, and Greek keypads.

• Help screen overlay provides pop-up description of the function of key buttons.

• Tutorials provide demonstration of the calculator’s capabilities by programmatically stepping through equation creation and unit conversion examples.

Equation Creation and Display

• Equations are created and displayed in their natural form, as they would appear in a textbook.

• Number Mode allows equations based on y (dependent variable) and x (independent variable) to be quickly created, solved, and have unit conversions carried out on the dependent variable.

• Variable Mode allows equations with more complex variables to be created:

• Unit conversions can be carried out on result.

• Super- and subscripting of variables.

• Functions include square root, squared, x to any power, log, ln, 10 to any power, e to any power, factorial, trigonometric (including inverse), hyperbolic (including inverse).

• Button selector allows the variable symbol or its value to be displayed in the equation.

• Previously used equations are maintained in memory and can be re-accessed by means of a drop-down selection window.

Unit Conversions

• Unit conversions are made simultaneously, and are displayed as a table of all units of the same category.

• New units can be created and saved to the library, using the base units (m, s, g, ft, lb, etc).

• New units are easily created using picker dials for the metric prefix (k, M, G, etc), base units, and power of 1, 2, 3, etc.

Constant Libraries

• Physics constant library.

Constants can be saved to libraries under user-defined categories.

Other Features

• E-mail contact is accessed through a button provided in the Help/Tutorial screens.

• Memory stack maintains values, variable symbols, and equation names of an unlimited number of previous calculations, which can be easily accessed for future calculations.

• Multiple answers for implicit equations are saved to the memory stack.

• Period or comma can be used as decimal separator.

• Degrees or radians for trigonometric functions.

• Decimal or Scientific Notation, and number of significant digits can be easily specified.
