GD-13 Graphing Calculator
A full-featured scientific and graphing calculator inspired by the TI-83, built for quick calculations and function visualization.
Basic Calculations
Type numbers and operators directly or use the buttons. Press ENTER to evaluate. Supports standard operations (+, −, ×, ÷), exponents (^), and parentheses.
Scientific Functions
Use SIN, COS, TAN, LOG, LN, √, and ABS. Press 2nd first to access inverse trig functions (sin⁻¹, cos⁻¹, tan⁻¹), π, and e^.
Graphing Functions
Press Y= to enter up to 6 functions using X as the variable. Examples: X^2, sin(X)*3, 2*X+1. Press GRAPH to plot.
Window & Trace
Press WINDOW to adjust the viewing range (Xmin, Xmax, Ymin, Ymax). Use TRACE to move a cursor along your functions and read coordinates. Arrow keys navigate.
Keyboard Shortcuts: Type numbers and operators directly. Use X for the variable, Enter to evaluate, Backspace to delete, Esc to clear or exit modes, and arrow keys for navigation.
