1
State the central method of The Fundamental Theorem as an Evaluation and Accumulation Principle and list the conditions that must be checked.
Faculty solution: Use connecting derivative and integral forms of the Fundamental Theorem. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
Evaluate ∫₀²(3x²+1)dx.
Faculty solution: An antiderivative is x³+x; the value is 10.
3
If G(x)=∫₁^{x²} cos(t)dt, find G′(x).
Faculty solution: By FTC and the chain rule, G′(x)=2x cos(x²).
4
A learner makes an error by confusing signed accumulation with total accumulation or omitting the constant of integration. Explain the first invalid step and repair the reasoning.
Faculty solution: The first invalid step is confusing signed accumulation with total accumulation or omitting the constant of integration. Return to the governing definition or theorem, restore the missing condition, and verify the corrected result.
5
Create a short application of The Fundamental Theorem as an Evaluation and Accumulation Principle in accumulated change, motion, flow, and model validation. 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 accumulated change, motion, flow, and model validation.
6
Describe two independent ways to verify a result from The Fundamental Theorem as an Evaluation and Accumulation Principle.
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.
