How to Use This Calculator
  1. Switch between Calculator, Graphing, and Conversions using the top tabs.
  2. Calculator — Standard mode: Tap or type basic arithmetic (+, −, ×, ÷, %). Scientific mode: Access trig, logs, exponents, memory, and 2nd-function keys like a TI-84. Programmer mode: Bitwise operations (AND, OR, XOR, NOT, shifts) with live HEX/BIN/OCT display. Statistics mode: Enter comma-separated data points, then tap stat buttons (n, Σx, x̄, σₓ, sₓ). Physics mode: Insert physical constants (c, G, h, kB, Nₐ) directly into expressions. Chemistry mode: Insert atomic masses from the periodic table, compute pH/pOH, and work with Ka/Kb/Kw. Use keyboard shortcuts (0-9, +-*/, Enter, Esc, ^, Ctrl+Z) for faster input.
  3. Graphing — Standard mode: Plot up to 6 functions simultaneously with color-coded curves and visibility toggles (eye icon). Click 'Examples' for presets like Trig, Polynomials, or Exponential vs Log. Use the Table button to view a table of values, and Export PNG to save your graph. Calculus mode: Enter a function to see its derivative overlaid on the graph, compute the definite integral over the visible range, find roots and critical points, and draw a tangent line at any x-value. Parametric mode: Define x(t) and y(t) to plot parametric curves — add a second curve for comparison, and view bounding box and arc length estimates. Polar mode: Enter r(θ) to plot polar curves with automatic max-r detection — add a second polar function to overlay. Limits mode: Evaluate one-sided or two-sided limits numerically with left/right approach visualization and continuity detection.
  4. Conversions — Pick from 14 categories (Length, Weight, Temperature, Volume, Area, Speed, Energy, Pressure, Time, Data Storage, Cooking, Fuel Economy, Color Codes, Number Bases). Select 'from' and 'to' units, enter a value, and see results instantly. Use the swap button to reverse direction. Color Codes mode shows HEX, RGB, HSL, HSV, and CMYK simultaneously. Number Bases mode converts between binary, octal, decimal, and hexadecimal.
  5. Pan the graph by clicking and dragging, zoom with the scroll wheel or ±buttons, and use the arrow pad to navigate. Pinch-to-zoom works on touch devices. Adjust X/Y window bounds under 'Show window settings' for precise control.
