Online Scientific Calculator
A comprehensive online scientific calculator designed for engineering, physics, algebra, trigonometry, and calculus problems.
How it works
Processes algebraic inputs, trigonometry (sin, cos, tan, inverse, hyperbolic), logarithms (ln, log10, log2, arbitrary base), powers, and roots using IEEE 754 floating-point precision.
Formula
f(x) in { sin(x), cos(x), tan(x), ln(x), e^x, x^y, y√(x), n! }
Executes high-precision mathematical, trigonometric, and transcendental operations with degree/radian angular support.
| Symbol | Variable | Unit | Description |
|---|---|---|---|
| A | First input operand or angle | unitless | |
| B | Secondary operand (exponent, root, or divisor) | unitless |
Worked example
sin(45°) in Degree Mode
- A:
- 45
- Operation:
- sin
- Mode:
- Degrees
sin(45°) = √2 / 2 ≈ 0.70710678.
Limitations
Numbers exceeding 10³⁰⁸ overflow to Infinity in accordance with standard 64-bit IEEE 754 precision.
Frequently asked questions
What is the difference between Radian and Degree mode?
Degrees divide a full circle into 360 units (common in geometry and navigation), whereas Radians measure angles based on arc length (2π radians = 360°, essential for calculus and physics).
How do memory buttons (MC, MR, MS, M+, M-) work?
MS stores the current number into memory, MR recalls it to display, M+ adds to memory, M- subtracts from memory, and MC clears memory to zero.
What is the maximum factorial this calculator can compute?
Factorials up to 170! (approx. 7.257 × 10³⁰⁶) can be calculated within standard double-precision floating point limits.
