## What is Matheo?

Matheo is a fast graphing calculator for iPhone and iPad.

GRAPH ANYTHING
• Functions like y = x² − 3x + 1, sin(x), 1/x and √x, with poles and jumps drawn correctly
• Equations in x and y: circles (x² + y² = 9), hyperbolas (xy = 1), and curves such as sin(x) = cos(y)
• Vertical lines, many curves at once, each in its own color

WRITE MATH NATURALLY
• Type 2x, ax² + bx + c, |x|, n!, sin²(x) and log₂(x)
• A typeset preview shows fractions, powers and roots as they appear on paper
• Its own math keyboard, so every symbol is one tap away: fractions, powers, roots, absolute value, subscripts, functions, letters and Greek

EXPLORE
• Define a = 2 to get a slider, then watch the graph change as you drag
• Tap a curve to see intercepts, maxima, minima and intersections
• Slide along a curve to read values, slope and tangent line, and shade a definite integral

SCIENTIFIC CALCULATOR
• Degrees and radians, inverse functions, ans, history
• Exact fractions and scientific notation

KEEP YOUR WORK
• Projects save automatically
• Share your graph as an image or copy the expressions

Works in light and dark mode, portrait and landscape, with Dynamic Type and VoiceOver.
