And one way to think about it is, pi over two is not in the domain of tangent of x. And so this limit actually turns out it doesn't exist. In general, if we're dealing with sine cosine tangent or cosecant secant or cotangent, if we're taking a limit to a point that is in their domain, then the value of the limit is going to be the same thing as the value of the function at that point. If you're taking a limit to a point that's not in their domain, there's a good chance that we're not going to have a limit. So here, there is no limit. And a way to deduce that is that pi over two is not in tangent of x's domain. If you were to graph tan of x, you would see a vertical asymptote at pi over two.
