To estimate the value of 1.984 using local approximation, we can round the number to a nearby value that is easier to calculate. In this case, we can round 1.984 to 2. This is because when we look at numbers that are close to 1.984, 2 is the nearest whole number.
Next, we can also consider using linear approximation if we have a function that models the value around this point. For instance, if we had a function defined as f(x), we could take the derivative at a point close to 1.984 (like 2) to help refine our estimate. However, for simple estimations, rounding is often sufficient.
In summary, the local approximation for 1.984 is approximately 2. This provides a quick and practical estimation that is useful in many contexts.
