Yep. 1/-inf = zero as well.
Limits are good for approximating the value of a function that never actually reaches a value but gets closer and closer without ever getting there.
There technically is no value of tan(pi/2) because the tangent function never reaches pi/2, rather it asymptotically approaches it, with the value going to infinity.
So when you evaluate it within a mathematical expression, you can use the limit.

"There remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking." ~Christopher Hitchens, god is not Great
