Trigonometric and hyperbolic functions

This section describes functions for performing trigonometric and hyperbolic operations. In all of the functions, the arguments are expressions resolving to angles measured in radians, where x should be interpreted as a real number.

All angles are measured in radians.

All functions can be used in both the load script and in chart expressions.


The following script code loads a sample table, and then loads a table containing the calculated trigonometric and hyperbolic operations on the values.

SampleData: LOAD * Inline [Value -1 0 1]; Results: Load *, cos(Value), acos(Value), sin(Value), asin(Value), tan(Value), atan(Value), atan2(Value, Value), cosh(Value), sinh(Value), tanh(Value) RESIDENT SampleData; Drop Table SampleData;
