Undefined is a term used when a mathematical result has no meaning. More precisely, undefined values occur when an expression is evaluated for input values outside of its domain. ( 1 if no complex numbers) ( 2 if no complex numbers) ( units in radians, no complex infinity)
To put matters straight: Division is a function q:RÃRâ,(a,b)â¦q(a,b)=:ab , whereby q(a,b) is the unique number xâR such that bx=a. When we say that a0 is undefined then this means no more and no less than that the pair (a,0) is not in the domain of the function q(â,â). Now to your three ways of understanding undefined in the realm of division by 0: If a0 could be any number, say =13, then this would enforce 13â0=a, which is wrong when aâ 0.
