Practice unit 4b mixed practice with structured problems that require method selection, justification, and error control.
A complete solution preserves the series identity, interval, endpoint logic, and approximation claim as one chain.
Write the objective and conditions first, solve independently, then use one answer reveal to repair the earliest incorrect decision.
Checking algebra while leaving the convergence domain or error certification unstated.
Work in three passes
First, classify. Name the derivative idea or rule before writing algebra. This separates a recognition error from a calculation error.
Second, solve without the key. Record a complete attempt, including bounds, constants, domains, units, or interpretation when the prompt asks for them.
Third, reveal one answer at a time. Compare the first line where your work differs, close the answer, and redo that item from a blank start.
