Frequently Asked Questions
Are trigonometric functions in degrees or radians?
By standard default, trigonometric functions on this calculator evaluate angle arguments in degrees.
What is the difference between log and ln?
log refers to common logarithm (base 10), while ln represents natural logarithm (base e ≈ 2.71828).
Does the calculator follow order of operations (PEMDAS)?
Yes, all expressions strictly follow standard mathematical operator precedence (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
