Hi
This is more of an intuitive question than a question that has a definitive answer.
When you are evaluating limits, say a limit of f(x) as x approaches 0, you can cross cancel terms of x that appear in the f(x) because x is not actually zero. However when you are done cancelling and have your limit in its simplest form it then appears as if you treat x as if it were 0 to get the limit.
This can seem a touch confusing. In other words, 'one minute x isn't 0 but next minute we may as well assume it is.' I was wondering if any of you seasoned experts in this subject had any time-tested pearls of wisdom that make this seem less confusing.
thanks
