What does "t-minus" mean when counting down to rocket liftoff?
When time is represented on a graph or timeline or drawing, convention shows time increasing positive in the right direction and increasing negative (minus) to the left direction.
In other words, you are timing negatively with numbers of increasing value from a future fixed time, starting with an exact time the rocket has to liftoff and planning every event backwards to the present.
Ahead of a set liftoff time, T-minus can be measured in seconds, minutes, hours, days, weeks, months, and years.

"T-minus" is a term used in rocket launches to indicate the time remaining until liftoff. It signifies the countdown, with "T" representing the time when the rocket is scheduled to launch. So, when you hear "T-minus," it means counting down to the moment of liftoff.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
