Unexpected behavior of Maple
I'm getting some strange behavior in Maple, and was hoping some of you could help me find out what's happening.
I type in this expression :
Now it seems quite straight forward that the roots of y(x) are i, -i, and 2.
Now when I ask Maple to find the roots for me:
I get this responce:
Maybe Maple can't handle 4-th order roots, fair enough. But the surprising part is when I make Maple calculate y(2) for me. The answer I get is:
How can that be?
I'm running Maple 11 btw.
