Parse equation and simple function

Hi! The simple function and equations always give me issues. And it’s probably something ridiculous and small that I am overlooking but I cannot get slide 12 input5 to give the correct feedback when I enter the answer. They should be entering xtan(15)=43

CL uses radians, so it’s probably not evaluating correctly for that reason. If you use a graph (and set it to degrees), you can send the lhs into the graph as a function:

hidden: true
function(`f`): input5.script.lhs

and evaluate in the graph.
In your input use the variable, C_{heck}, from the graph instead of your inequalities:

correct= yourGraphName.number(`C_{heck}`)=0 and eq.rhs=`43`

Thank you! That worked!
