Frequently Asked Questions
Can I enter full expressions?
Yes, the Basic tab supports expressions like 2+3*4, sin(45), sqrt(16), and pi*2.
What angle mode is used?
Trigonometric functions use degrees. Inverse functions return degrees.
What is the largest factorial supported?
Factorials up to 170! are supported due to JavaScript number limits.
Are all constants included?
The calculator includes π, e, φ (golden ratio), c (speed of light), and g (gravity).
People Also Ask
What is the difference between log and ln?
log is base-10 logarithm, while ln is the natural logarithm (base e).
How do I calculate sin(30 degrees)?
Enter 30 in the Trigonometry tab and click the sin button. Result is 0.5.
What does factorial mean?
Factorial of n (n!) is the product of all positive integers from 1 to n.
