Scientific Calculator
Advanced scientific, graphing, and matrix calculations with a safe recursive descent expression parser.
About This Scientific Calculator
Safe Expression Parser
Uses a recursive descent parser — no eval(). Handles operator precedence, parentheses, implicit multiplication, and scientific functions.
Graphing Engine
Plot any function on an interactive canvas. Adjustable X/Y ranges, grid lines, and real-time plotting. Supports all scientific functions.
Calculus & Matrix
Numerical integration (Simpson's rule) and differentiation (central difference). 2×2 and 3×3 matrix operations with determinant, transpose, and multiplication.
Statistics
Mean, median, mode, standard deviation, variance, permutations (nPr), combinations (nCr), and Fibonacci sequence generation.
Keyboard Support
Type expressions directly: numbers, operators (+, -, *, /, ^), parentheses, Enter for result, Backspace to delete, Escape to clear.
Degrees & Radians
Toggle between degree and radian mode for trigonometric functions. Works for sin, cos, tan, and their inverses.
💡 Quick Tips
- Implicit multiplication works:
2π,3sin(π/2) - ANS stores the last result — type
ANSor click the button to reuse it - Graph mode supports any valid expression with
xas variable:sin(2x) + cos(x) - Factorial works on numbers and expressions:
5!or(3+2)! - Matrix mode supports addition, subtraction, multiplication, determinant, and transpose
- Integration uses Simpson's rule with adjustable step count for accuracy
⚡ Pro tip: You can switch between modes without losing your current expression. The calculator preserves your input as you switch between Basic and Scientific views.
Save Configuration Snapshot
Save current parameters to your dashboard for instant one-click reloading.
