Hi People (Hi)

I search a method for expand all terms of Sum or Product in Derive 6

example :

\(\displaystyle \sum_{i=1}^{10} i^2 = 385\) not this (Shake)

\(\displaystyle \sum_{i=1}^{10} i^2 = 1+4+9+...\) <-- I need this ! (Nod)

what I must try ? Thanks. (Bow)

Firing up the old T2110 which has Derive 5 on it, it seems you should just simplify the \(\displaystyle \sum_{i=1}^{10}i^2\) expression rather than expand it which appears to be what you have done.
