@sand15 answered my question but I cannot reply to him. Preview is ok. When I press 'Submit' there is a blue bar and a dot running from the left to the right. It never stops. Why?

I want to define a piecewise function. How do I test if a variable t is in a definite open or closed real range?

I have a non-linear deq of 2nd order which I want to solve numerically. The integration should stop if the integrated variable exceeds a certain value, i.e. phi(t)>phi_ end or equivalently phi(t)-phi_end>0. Maple doesn't accept this type of event and the test phi(t)=phi_end doesn't catch (obviously). How to work around?

Good morning

Why doesn't Quotient(x,y,z) not work within a procedure whereas it works well standing alone? See example.

Is there a possibility to test the result of a numerically solved deq?
