Logical Implication versus Approaches

  1. Dec 21, 2009 #1
    Both the logical implication and approaches use the same symbol. Have the two ever been famously confused? Is it implied that one or the other only be used in a specific context?

    p --> q

    x --> positive infinity

    hehe, nice pun.

    I don't think it would ever be hard to tell from the context which one is used. The "approach" symbol is used in specific sentences like "f(x)-> f(a) if x-> a", or under the [tex]\lim[/tex] symbol.

    Furthermore, the logical implication symbol [tex]\to[/tex] is mostly used in the specific area of logic. In other areas of mathematics one often uses [tex]\Rightarrow[/tex] for an implication.
