Scientific Calculator

Why is this "university-level"?

Unlike a basic calculator, this tool runs on a full math engine. It evaluates expressions exactly, respecting standard order of operations (PEMDAS/BODMAS).

Features

• Trigonometry: Uses radians by default. To work in degrees, append the degree unit: sin(90 deg).
• Combinatorics: Use nCr(n, k) for combinations and nPr(n, k) for permutations.
• Constants: Exact values for π (pi) and e (Euler's number).
• Keyboard: Type directly into the display and hit Enter to calculate.
