Evaluate proper definite integrals using a checked antiderivative and upper-minus-lower endpoint values. Prerequisites: elementary primitives, continuity and signed integrals. Explain constant cancellation, preserve oriented bounds and reject a proper-integral shortcut across a singularity. No substitution or improper-integral evaluation is required.

Use continuity and short-interval accumulation to recover a local rate directly from an integral with a moving upper limit. Prerequisites: continuity, the derivative definition and geometric accumulation. Distinguish the dummy variable from the input, and examine discontinuities without assuming that a missing hypothesis settles the conclusion.

Check your choice of geometric areas, Riemann sums, integral properties and table-based estimates. Use signs, units and available information to justify what is exact and what is approximate. Prerequisites: the accumulation chapter. No FTC shortcuts; no calculator is needed, and all requested estimates are exact finite-rule arithmetic.

Read signed areas from exactly specified rate graphs, change the reference input, and combine an initial quantity with net change. Prerequisites: geometric areas, oriented intervals and integral additivity. No antiderivative or differentiation shortcut is needed.
Oct 28, 2026
Transform integration bounds consistently and track orientation when the inner expression decreases. Prerequisites: indefinite substitution and definite FTC evaluation. Compare coherent evaluation routes, diagnose mixed-variable bounds and interpret a signed accumulated rate.
Oct 28, 2026
Carry out a complete change of variable, including the differential, all remaining terms and back-substitution. Prerequisites: reverse-chain recognition and standard primitives. Check polynomial, radical, exponential and short trigonometric patterns while preserving real domains.
Oct 28, 2026
Recognize when a composite expression carries its inner derivative and decide whether a constant rescaling is enough. Prerequisites: chain rule and standard power/exponential derivatives. Practice structural matches, near-matches and verification before formal substitution.
Oct 28, 2026
Check both directions of the Fundamental Theorem of Calculus: evaluate signed integrals, differentiate accumulation, and connect rates to amounts. Prerequisites: elementary primitives, continuity and the chain rule. Diagnose bounds, theorem conditions and graph interpretation; no new integration method is introduced.
Oct 28, 2026
A mixed checkpoint on direct primitives, complete substitutions, exponential and logarithmic patterns, inverse-trigonometric scaling, and domain checks. Requires the Chapter 14 practice skills. Each problem is independent; attempt the calculation or justification before inspecting the choices.
Oct 28, 2026
Choose efficient elementary integration methods by simplifying, identifying a direct rule, or making a complete substitution. Requires standard primitives and the exponential, logarithmic, and inverse-trigonometric patterns. Diagnose failed methods and choose a justified numerical route when appropriate.
Oct 28, 2026
Practice scaled inverse-tangent and inverse-sine primitives, affine inner inputs, and real-domain restrictions. Requires inverse-trigonometric derivatives and complete substitution. Select patterns deliberately and verify scale factors by differentiation.
Oct 28, 2026
Practice recognizing exponential and logarithmic reverse-chain patterns, matching differential factors, and checking real domains. Requires elementary exponential/logarithmic derivatives and consistent substitution. Includes method comparisons and a short accumulation model.
