1
State the central method of Method Selection, Units & Geometric Verification and list the conditions that must be checked.
Faculty solution: Use defending bounds, method, orientation, and reasonableness. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
Which method is usually simpler for rotating y=x², 0≤x≤1, about y-axis?
Faculty solution: Cylindrical shells in x avoid solving x=√y.
3
A volume integral produces units of cm². Diagnose the issue.
Faculty solution: A length factor is missing; volume must have cubic units.
4
A learner makes an error by using the wrong radius, height, or orientation in a geometric setup. Explain the first invalid step and repair the reasoning.
Faculty solution: The first invalid step is using the wrong radius, height, or orientation in a geometric setup. Return to the governing definition or theorem, restore the missing condition, and verify the corrected result.
5
Create a short application of Method Selection, Units & Geometric Verification in design, manufacturing, architecture, material estimation, and geometric modelling. 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 design, manufacturing, architecture, material estimation, and geometric modelling.
6
Describe two independent ways to verify a result from Method Selection, Units & Geometric Verification.
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.
