Hello everyone,
A basic to intermediate Moodle user here. I need some help with a Stack question.
So, the answer to my moodle quiz is (tanh(sqrt(g*H/2)*t/L)). This can be written in several forms
But if a student alters the answer a bit, i.e. takes the L inside the sqrt() and writes it as L^2, (tanh(sqrt(g*H/(2*L^2))*t))
Moodle does not consider it equivalent to the answer provided. I have tried using AlgEquiv, SubstEquiv, and SysEquiv as my answer test but to no avail.
To circumvent this problem I decided to add a second node with the other variant of the answer.
This
is where the problem starts, Moodle checks for equivalence between the
Tans and Sans at Node 1 and gives out a result but when the answer is
considered not equivalent or "false" it moves on to Node 2, and this
where I always get a "TEST_FAILED" and it does not check for
equivalence. Could someone please help me solve this problem or guide me
to any other workaround to this problem? Thank you.
