1
State the central method of Integral Test, p-Series & Continuous Comparison and list the conditions that must be checked.
Faculty solution: Use connecting decreasing positive terms to improper integrals. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
Determine Σ1/n^{3/2}.
Faculty solution: Converges.
3
Determine Σ1/√n.
Faculty solution: Diverges.
4
A learner makes an error by confusing term limits with series convergence. Explain the first invalid step and repair the reasoning.
Faculty solution: The first invalid step is confusing term limits with series convergence. Return to the governing definition or theorem, restore the missing condition, and verify the corrected result.
5
Create a short application of Integral Test, p-Series & Continuous Comparison in repeated processes, finance, approximation, fractals, and infinite accumulation. Define variables and identify the quantity an integral, differential equation, sequence, or series would measure.
Faculty solution: A defensible response defines variables and units, states assumptions, builds the correct mathematical object, and interprets its value in repeated processes, finance, approximation, fractals, and infinite accumulation.
6
Describe two independent ways to verify a result from Integral Test, p-Series & Continuous Comparison.
Faculty solution: Use an exact structural check such as differentiation, substitution, partial sums, or theorem hypotheses; then compare with numerical, graphical, dimensional, or limiting evidence.
