How to use the calculator
- Tap the numbers and operations, or type them on your keyboard.
- Use sin, cos, tan, log, ln, roots, and powers for scientific work. Deg switches the angle unit to radians.
- Press equals. The calculation stays above the result.
12 + 3 is 15. sin of 90 degrees is 1, and 2 raised to 10 is 1024. The 2nd key switches sine, cosine, and tangent to their inverses. A trailing operator, a missing parenthesis, and division by zero are rejected.
Frequently asked questions
Does the calculator upload the sum?
No. The expression is calculated in your browser and is not sent to a server.
Are angles in degrees or radians?
Degrees, until you press Deg. The label above the result changes to Radians. Inverse sine, cosine, and tangent use the same unit.
