13096	find_maximum_on_interval fails when used with a sage function	aginiewicz	jason, jkantor	"The function find_maximum_on_interval fails when used with a sage function that is passed as an argument:

{{{
sage: f(x) = sin(x)
sage: find_maximum_on_interval(f, 0, 2*pi)
Traceback (click to the left of this block for traceback)
...
RuntimeError: ECL says: THROW: The catch MACSYMA-QUIT is undefined.
}}}
while all of:
{{{
sage: find_minimum_on_interval(f, 0, 2*pi)
(-1.0, 4.7123889815323858)
sage: f.find_minimum_on_interval(0, 2*pi)
(-1.0, 4.7123889815323858)
sage: f.find_maximum_on_interval(0, 2*pi)
(1.0, 1.570796325647202)
}}}
works. This was kind of unexpected, esp that documentation says about providing a function as an argument."	defect	closed	minor	sage-duplicate/invalid/wontfix	numerical	duplicate				N/A	Andrzej Giniewicz
