1
State the central method of Antiderivative Families, Constants & Initial Conditions and list the conditions that must be checked.
Faculty solution: Use reconstructing antiderivative families and using initial conditions to determine constants. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
Find F if F′(x)=6x²−4 and F(1)=5.
Faculty solution: F(x)=2x³−4x+C; F(1)=5 gives C=7, so F(x)=2x³−4x+7.
3
Evaluate ∫(3x⁴−2/x)dx.
Faculty solution: (3/5)x⁵−2ln|x|+C.
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 Antiderivative Families, Constants & Initial Conditions 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 Antiderivative Families, Constants & Initial Conditions.
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.
