A scientific calculator for square roots, powers, trigonometry, and logarithms, with support for constants like pi and e. Runs entirely in your browser.
How to use
- Type an expression, or use the function and number buttons.
- Use ^ for powers and function buttons like sqrt, sin, cos, tan, and log.
- Press = or Enter to evaluate.
Frequently asked questions
Are the trigonometric functions in degrees or radians?
Trig functions (sin, cos, tan) use degrees, which is what most casual users expect. So sin(30) returns 0.5.
How do I calculate powers and roots?
Use ^ for exponents (for example 2^10 = 1024) and the sqrt function for square roots (sqrt(16) = 4).
Can I use constants like pi?
Yes, type pi or e and they're substituted with their values before evaluation.
