Understand limits to infinity

When `x->∞`, `1/x` appoachs zero, but is never equal zero!

Understanding limits to infinity When x->∞, what is the exact number of x? We don’t know, x is undefined. ∞ is not a number, is a idea of having a greater number than you give. When x->∞, 1/x appoachs zero, but is never equal zero! When n -> ∞, does sin(1/n) / (1/n) have meaning? I used to thought 1/n = 0 while n->∞, but 0 cannot be divided, So I was confused.
