- AreEqual[ <Object>, <Object> ]
- Decides if the objects are equal.
Normally this command computes the result numerically. This behavior can be changed by using the Prove command.
- Example:
AreEqual[Circle[(0, 0),1],x^2+y^2=1]
yields true since the two circles have the same center and radius.
- Note:
AreEqual[Segment[(1, 2), (3, 4)], Segment[(3, 4), (1, 6)]]
is different fromSegment[(1, 2), (3, 4)] == Segment[(3, 4), (1, 6)]
as the latter compares just the lengths
Note: See also AreCollinear, AreConcyclic, AreConcurrent, ArePerpendicular, AreParallel commands.
