Author a formula sub-type
This sub-type is authored by selecting the Formula option from the Sub-type drop-down list during mathematical formula question authoring.
Examples of accepted syntax for defining the Answer field value for this sub-type are:
(e^x)*sin(x^2)5*x^4
The formula sub-type Answer field:
Accepts numbers, formulas, and more advanced operations (Example — trigonometric functions, logarithms, etc.).
Accepts equivalent responses.
Doesn't accept equations (expressions consisting of two components separated by an
=sign).
Example of this sub-type
Question statement:
y=x5
What is the derivative of y with respect to x?
Enter only the expression for the derivative, omitting "y=..."
Answer field syntax:
5*x^4
Example of this sub-type with an algorithm
Question statement:
y=x$n
What is the derivative of y with respect to x?
Enter only the expression for the derivative, omitting "y=..."
Algorithm:
$n = rint(20) + 2;
Answer field syntax:
$n*x^($n-1)
