Parameters
|
|
|
topic
|
-
|
name; specifies the topic for information
|
|

-
|
name; mathematical function

Description
|
|
|
•
|
The Get(topic, math_function) function returns the topic information on the function math_function. If the requested information is not available it returns NULL.
|
|
•
|
The topic argument must be one of:
|
|
•
|
To display the list of possible values for the math_function argument, use the FunctionAdvisor(known_functions) function. For more information, see FunctionAdvisor/known_functions.
|
|
•
|
The Get(topic, math_function) function is equivalent to FunctionAdvisor(topic, math_function), but does not attempt to match misspelled topic or math_function arguments to the correct names. For more information, see FunctionAdvisor.
