1. Scientific calculator
- arithmetic expressions +,-,*,/ (/ is for both fraction and division)
- square root, cube and higher roots (hold root key)
- exponent, logarithms (ln, log)
- trigonometric functions sin π/2, cos 30°, ...
- hyperbolic functions sinh, cosh, tanh, ... (hold "e" key to switch)
- inverse functions (hold direct function key)
- complex numbers, all functions support complex arguments
- derivatives sin x' = cos x, ... (hold x^n key)
- fractions 1/2 + 1/3 = 5/6, use space to enter mixed values 3 1/2
- linear equations x + 1 = 2 -> x = 1
- quadratic equations x^2 - 1 = 0 -> x = -1, 1
- approximate roots of higher polynomials
- systems of linear equations, write one equation per line, x1+x2=1, x1-x2=2
- polynomial division
- matrix and vector operations, dot product, cross product, determinant, inverse, norm, transpose, trace
2. Graphing calculator
- multiple functions
- implicit functions up to 2nd degree (ellipse 2x^2+3y^2=1, etc.)
- polar graphs (r=cos2θ)
- function roots and critical points on a graph, tap legend to turn on and off (top left corner), hold to display a list
- scrollable and resizable
- tracing function values and slopes
- fullscreen graph in landscape orientation
- save graphs as images
3. Function tables
- multiple functions
- scrollable and resizable
- adjustable precision and step
- save tables as csv
