2 cards from this section. Quick, good the night before a test.
Define interpolation in your own words.
Think about where the unknown value lies in relation to the known points.
What is the significance of the error term in interpolation?
Consider why knowing accuracy is important in calculations.
What does the error term in interpolation help us understand?
Think about what ensures our calculations are safe.
True or False: The behavior of a function is irrelevant to the accuracy of interpolation.
Consider how different functions might change over intervals.
Given a function with known values at (0, 0), (1, 1), and (2, 4), estimate the error while interpolating at x=1.5 using the general error term.
Use the appropriate derivatives and evaluate at the midpoint.
In a design problem, you need to interpolate a series of measurements for structural integrity. Discuss the challenge of estimating error when the dataset is unevenly spaced.
Look at the distances between values and how they might affect interpolation.
