When I decided I should come up to speed on Modules, I found a simple

writeup on:

http://www.tutorialspoint.com/ruby/ruby_modules.htm.

The example worked fine as far hooking up the Module routines to the

main code went, but it didn’t work because the author didn’t finish

defining some of the methods, which I discovered by running the code.

I fleshed out the trig functions by using the math module, but that

bombed.

I posted my code and the error messages at

http://www.pastie.org/1596692.

I’m running Ruby 1.8.6 over WinXP-Pro/SP3. I’m stuck on the complaint

that the math module cannot be found

However, the following seems to show that I’ve got the math module

installed:

K:>gem list -l math

*** LOCAL GEMS ***

math (0.0.1)

mathml (0.8.1)

So, I can’t see what’s wrong. Any ideas?

Thanks in Advance,

Richard
