# Functions

Choose a function in the lower part of the Elements pane. These functions are also listed in the context menu of the Commands window. Any functions not contained in the Elements pane need to be typed manually in the Commands window.

The following is a list of all functions that appear in the Elements pane. The icon next to the function indicates that it can be accessed through the Elements pane (menu View - Elements) or through the context menu of the Commands window.

### List of functions

Natural Exponential Function

Inserts a natural exponential function. You can also type func e^<?> directly in the Commands window.

Natural Logarithm

Inserts a natural (base e) logarithm with one placeholder. You can also type ln(<?>) in the Commands window.

Exponential Function

Inserts an exponential function with one placeholder. You can also type exp(<?>) in the Commands window.

Logarithm

Inserts a common (base 10) logarithm with one placeholder. You can also type log(<?>) in the Commands window.

Power

Inserts x raised to the yth power. You can also type <?>^{<?>} in the Commands window. You can replace the ^ character with rsup or sup.

Sine

Inserts a sine function with one placeholder. You can also type sin(<?>) in the Commands window.

Cosine

Inserts a cosine function with one placeholder. You can also type cos(<?>) in the Commands window.

Tangent

Inserts a tangent function with one placeholder. You can also type tan(<?>) in the Commands window.

Cotangent

Hyperbolic Sine

Inserts a hyperbolic sine with one placeholder. You can also type sinh(<?>) in the Commands window.

Square Root

Inserts a square root symbol with one placeholder. You can also type sqrt(<?>) in the Commands window.

Hyperbolic Cosine

Inserts a hyperbolic cosine symbol with one placeholder. You can also type cosh(<?>) in the Commands window.

Hyperbolic Tangent

Inserts a hyperbolic tangent symbol with one placeholder. You can also type tanh(<?>) in the Commands window.

Hyperbolic Cotangent

nth Root

Inserts an n-th root function with two placeholders. You can also type nroot n x in the Commands window.

Arc Sine

Inserts an arc sine function with one placeholder. You can also type arcsin(<?>) in the Commands window.

Arc Cosine

Inserts an arc cosine symbol with one placeholder. You can also type arccos(<?>) in the Commands window.

Arc Tangent

Inserts an arc tangent function with one placeholder. You can also type arctan(<?>) in the Commands window.

Arc Cotangent

Inserts an arc cotangent function with one placeholder. You can directly type arccot(<?>) in the Commands window.

Absolute Value

Inserts an absolute value sign with one placeholder. You can also type abs(<?>) in the Commands window.

Area Hyperbolic Sine

Inserts an area hyperbolic sine function with one placeholder. You can also type arsinh(<?>) in the Commands window.

Area Hyperbolic Cosine

Inserts an area hyperbolic cosine function with one placeholder. You can also type arcosh(<?>) in the Commands window.

Area Hyperbolic Tangent

Inserts an area hyperbolic tangent function with one placeholder. You can also type artanh(<?>) in the Commands window.

Area Hyperbolic Cotangent

Inserts an area hyperbolic cotangent function with one placeholder. You can also type arcoth(<?>) in the Commands window.

Factorial

Inserts the factorial sign with one placeholder. You can directly type fact <?> in the Commands window.

You can also assign an index or an exponent to a function. For example, typing sin^2x results in in a function "sine to the power of 2x".

When typing functions manually in the Commands window, note that spaces are required for some functions (for example, abs 5=5 ; abs -3=3).
