Frequently asked questions
What can the scientific calculator do?
It evaluates a typed math expression with trigonometric functions, logarithms, square roots, exponents, powers, parentheses and the constants pi and e.
Does it work in degrees or radians?
Both. There is a degrees and radians toggle that controls how the trig functions such as sin, cos and tan interpret the angle you enter.
How do I raise a number to a power?
Use the caret symbol, so typing 2^10 gives 1024, and you can combine powers with parentheses for more complex expressions.
What is the difference between ln and log?
ln is the natural logarithm with base e, while log is the common logarithm with base 10, and both are available as separate functions.
Can I use pi and e in a calculation?
Yes. You can type pi and e directly and they are replaced with their full precision values when the expression is evaluated.
Is my expression sent to a server?
No. The calculator parses and evaluates your expression securely in the browser without using the JavaScript eval function, and nothing is uploaded.
How do inverse trig functions work?
Functions like asin, acos and atan return an angle from a ratio, and the result is shown in degrees or radians depending on your toggle setting.
Why do I need to close my parentheses?
The parser follows standard order of operations, so unbalanced parentheses produce an error because the expression cannot be interpreted correctly.
