[LON-CAPA-users] Having an equation or a range as a response

[Seema Ali]

Hi,
 
I'm super new to Lon Capa and I'm trying it out to see what I can do with it.  I have a huge list of questions but for now I'll just ask two.
 
A.  How to you set up the response (evaluation) so that a student can enter an equation.  For example:
1. x=4
2. y=5
3.  u^2 + v^2 = 2
 
B.  How do you set up the response (evaluation) so that a student can enter a range.  For example:
0. 1<x<=3
1.  -1/2 <= x < 1/2 or x>10
2.  empty set
3. all real numbers
 
Thanks.
