CalcPilot: Graphing Calculator

CalcPilot combines six calculators in one app for students, engineers and anyone who needs more than basic arithmetic.

Scientific
• Trigonometry in degrees or radians, logarithms, powers, roots and factorials
• Store values in variables and reuse them
• Equation solver: enter an equation and a starting guess to find a solution

Graphing
• Plot several functions at once, each in its own color
• Cartesian, polar (enter θ or theta) and parametric modes
• Curves are computed in the background, so plotting, panning and zooming stay responsive
• Pan and zoom, set the viewing window, and trace along any curve, including polar and parametric ones
• Find zeros, minimums, maximums and the intersection of two functions
• Table view of x and y values

Matrix
• Add, subtract, multiply and transpose
• Determinant, inverse and reduced row echelon form (RREF)

Statistics
• One-variable stats: mean, median, mode, quartiles and standard deviation
• Regression: linear, quadratic, exponential, power and logarithmic

Unit converter
Length, weight, temperature, area, volume and speed.

Standard
An everyday calculator with calculation history.

History and widget
• Search your calculation history, delete single entries with undo
• Home screen calculator widget for quick sums, saved to the same history
