If you like to compute the values of multiple functions at multiple points, please use "Create new table action":

After typing "Create new table" into action search box, enter the functions and the points into the table by clicking on. Enter functions on the first (Functions) column and the values on the first (Values) row. 


Then Gradarius computes the values of the functions as shown in the image above.
