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
