Scientific Calculator

The Scientific Calculator adds trigonometry, logarithms, exponents, roots, and constants like π and e to the standard four operations - everything a student, engineer, or scientist needs for coursework and quick checks.

Functions included

Trigonometry - sin, cos, tan and their inverses, in degrees or radians.
Logarithms & exponents - log (base 10), ln (natural log), e^x, and powers.
Roots & powers - square root, x^y, squares, and cubes.
Constants - π (pi) and e to full precision.

Degrees vs radians

Trigonometric results depend entirely on the angle mode. If sin(90) returns 1 you are in degrees; if it returns roughly 0.894 you are in radians. Always confirm the mode before trusting a trig result - it is the single most common source of error.

Frequently Asked Questions

How do I switch between degrees and radians?

Use the angle-mode toggle before entering a trigonometric function. Degrees are typical for geometry; radians are typical for calculus and physics.

What is the difference between log and ln?

"log" is the base-10 logarithm and "ln" is the natural logarithm (base e ≈ 2.71828). Use ln for growth, decay, and calculus problems.

Can it calculate powers and roots?

Yes. It supports squares, cubes, arbitrary powers (x^y), square roots, and can combine them within a single expression.

Is it accurate enough for engineering work?

It uses your browser's IEEE double-precision math, accurate to about 15 significant digits - sufficient for schoolwork and most engineering estimates.
