Tangent

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

Algildi

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

Gleiðbogaður sínus flatarmál

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

Gleiðbogaður kósínus flatarmál

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