+  LON-CAPA provides an easy interface for publishing your content pages,
+  problem resources, and sequences.

+ .
+  Metadata can often be thought of as a label on some bit of information
+  that can be useful to people or computer programs trying to use the data.
+  Without metadata, the person or computer trying to use the original information
+  would have to just guess what the original data is about.
+  For instance, if you create a problem and neglect to say in the title or
+  subject of the problem what it is about, then a human who wants to use
+  that problem would have to read the problem itself to see what it was about,
+  which is much more difficult then just reading a title.
+  A computer trying to do the same thing would just be out of luck; it is

+ One example of metadata you use all the time is the <TITLE> of a web page,
+  which usually shows up in the title bar of the browser.
+  That's information about the web page itself, not actually part of the

+ Formula response problems asks the student to type in a formula as an answer.
+  If the answer is
+ \begin_inset Formula \( 2x^{2}+4 \)
+ \end_inset
+ , the student is allowed to type
+ \begin_inset Quotes eld
+ \end_inset
+*x*x+4
+ \begin_inset Quotes erd
+ \end_inset
+ ,
+ \begin_inset Quotes eld
+ \end_inset

+ \begin_inset Quotes eld
+ \end_inset
+*x^2 + 14 - 10
+ \begin_inset Quotes erd
+ \end_inset
+ , or any other equivalent expression.
+  Formula Response problems have many of the same characteristics of Numerical
+  Response problems, including the ability to run scripts, dynamically generate
+  answers, etc.
+ \layout Standard
+ As you may know, it is extremely difficult to determine whether a given
+  expression is exactly equal to another expression in general.
+  For example, is
+ \begin_inset Formula \( \sin 2x=2\sin x\cos x \)
+ \end_inset
+ ? Symbolically proving it one way or another is impossible in general.
+  Therefore, LON-CAPA uses a sampling system.
+  If your answer and the student's answer agree at the sampling points within
+  your given tolerance factor, the student's answer will be accepted, otherwise
+  it will be rejected.
+ \layout Subsubsection
+ Sampling Specifications
+ \layout Standard
+ To specify where to sample the formulas to determine whether the student's
+  answer is correct, you need to put a sampling specification in the

+ , one could specify

+ x@2
+ \begin_inset Quotes erd
+ \end_inset
+ , which will sample the answers only at 2.

+ \layout Itemize
+ \begin_inset Quotes eld

+ The formula evaluator can not handle things of the form
+ \begin_inset Quotes eld
+ \end_inset
+ x + - y
+ \begin_inset Quotes erd
+ \end_inset
+ .
+  If you have a random variable that may be positive or negative (as in the
+  example following this section), you can try wrapping the references to
+  that variable in parenthesis.
+  As always, it is a good idea to try out several randomized versions of
+  your problems to make sure everything works correctly.
