Hello. I’m a novice with this program but I’m finding it hard to find suitable documentation.
I’d like to perform symbolic sums, but I cannot find the relevant function. I’m assuming it must exist because I can barely conceive of a CAS that does not feature them.
For example, I’d expect Sum(m,m,1,n) to return (n/2)*(n+1) (the well-known expression for triangular numbers) but all I get in return is the exact same input I gave.
So, please tell me what I should be using instead.
Thanks & apologies.
