You can enter the following notation in calcPad®.

Note: Typing a function name such as sin automatically adds parentheses to delimit the argument of the function. This works well most of the time, but as listed in the table, you might sometimes need to navigate out of the parentheses to modify your function, for example, to set the base of a general log function.

Alternative notations for trigonometric functions such as arcsin and sin-1 are graded identically.
