To calculate the time it would take for a spacecraft to reach the nearest star at 98% of the speed of light, we can use the formula for time dilation from special relativity. At 98% of the speed of light, the Lorentz factor is approximately 5.03. Given that the nearest star, Proxima Centauri, is about 4.24 light-years away, the time it would take for the spacecraft to reach it at 98% of the speed of light would be approximately 4.24 light-years divided by the Lorentz factor, which equals about 0.84 years or roughly 10 months from the perspective of the spacecraft.

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.
