How this scientific calculator works

This online scientific calculator lets you type complete expressions using numbers, operators and functions. You can mix parentheses, powers, square roots, trigonometric functions, logarithms and constants like π and e in a single line.

Angle mode can be switched between degrees and radians. When degrees are selected, functions such as sin(), cos() and tan() interpret the input as degrees instead of radians, which is convenient for school and everyday work.
