Dear @ppurka
thanks so much - i am now finally back at home with my trusty Macs and
hopefully will be able to do the above, eventually :)
For me this is entering an exciting new phase! Thanks again.

minimize(gg,[0,0])
works fine I cannot see anywhere in the reference manual where the

Would it perhaps help for me to post a simplified meta-code version of this

Hi again - thanks for that excellent new function - it's amazingly compact

Am I to deduce from this that what I was originally trying to do (ie

Hello all,
How can I evaluate
integral(sin(x^2),x,0,2)
to get a real value instead of the nasty expression involving erf() and I that
it spits out at me?

Hello,
I'm trying to simplify the list [pi/4..3*pi], which gives [(1/4)*pi, (1/4)*pi +
1, (1/4)*pi + 2, …] so that I get [pi/4, 5*pi/4, 9*pi/4, …]. Is there an easy
way to do this?

+1 to "Rigerous" testing of equality, but being able to rigorously
show if something is not equal is hard (and in many nontrivial cases
not possible). bool() should return true "if it can be shown to be

Errors should not under any circumstances be thrown if bool(x==y) is
inconclusive. It would break half of the code that depends on
symbolics, and would require try blocks around every if statement.
