What a finished MAT-FPX2200 Assessment 3 integration solutions looks like
The finished solutions treat an integral as a question about totals rather than as a symbol to process. Indefinite items show the antiderivative built term by term, with the substitution written as its own small change of variable, new variable defined, differential converted, and the original variable restored at the end. The constant appears on every indefinite result and is solved for whenever an initial condition is supplied. Definite items name what the region or the interval represents before any bound is written, and the bounds are then justified in a sentence tied to the question asked. Evaluation is shown at both limits and subtracted in the open. Each result ends in a total with units, and where a signed area appears the example says which part sits below the axis and why that matters.
How a MAT-FPX2200 Assessment 3 example is structured
The example organizes every item around the difference between finding an antiderivative and answering a question with one. Technique items come first and are written as a sequence of reversals: the rule recognized, the antiderivative proposed, the result differentiated back to confirm it, which is a check the criteria rarely require and always reward. Substitution items add a labeled change of variable and an explicit conversion of the differential, with the bounds converted too whenever the integral is definite. Application items open differently, with a sentence identifying the accumulating quantity and the interval over which it accumulates, since that identification is what selects the bounds. The computation then follows the same visible path, and the final subtraction is displayed rather than performed mentally. Each item closes on meaning, the number restated as a total of something, with the units the integrand and the variable together produced.
The accumulating quantity identified first
Application items name what is piling up and over what interval before a bound is chosen, because the bounds come from the question and not from the algebra.
Substitution written as a full exchange
The new variable, the converted differential and the restored original all appear on the page, so no step of the exchange happens off the record.
The constant kept alive to the end
Every indefinite result carries its constant, and where an initial condition is given the example solves for the constant instead of abandoning it.
Antiderivatives differentiated back as a check
Each proposed antiderivative is verified by differentiating it in one line, a habit that catches sign and coefficient slips before they reach the evaluation.
Totals reported with their units
The closing sentence states what quantity accumulated over what span, which is where the interpretation criterion lives and where bare numbers forfeit it.
Where marks go in MAT-FPX2200 Assessment 3
Integration is marked wrong rather than weak, and three failures account for most of it. Bounds that answer a different question lead: a correct technique run from zero when the interval the scenario described began elsewhere, producing a tidy number about nothing asked. The abandoned constant is second, dropped from an indefinite result or never solved despite an initial condition sitting in the problem statement. Third is the unconverted substitution, where the variable changes but the differential or the definite bounds stay behind, so the integral evaluated is no longer the integral posed. Points also go to signed area reported as total area with no mention of the axis, to antiderivatives never checked by differentiating back, and to totals delivered as bare numbers. Skipped lines cost the presentation criteria on their own.

MAT-FPX2200 Assessment 3 questions, answered
How much does the interpretation sentence really matter?
It usually carries its own criterion, and it is the sentence learners skip. An evaluated integral is a number; the assessment asks what accumulated, over which interval, in what units. The example writes that line under every applied item, and the line is short: a quantity, a span, a total. Omitting it leaves the applied half of the item unearned no matter how clean the antiderivative above it.
My section allows a calculator for definite integrals. Does that change the sample?
The value can come from a tool where your instructions permit it, but the surrounding work still gets graded. The example shows the integrand chosen, the bounds justified against the question and the result interpreted, then treats the computed number as one line among several. Sections vary on what may be automated, so send your instructions and the sample follows them rather than guessing.
Why check an antiderivative by differentiating it back?
Because it costs one line and catches the errors that are otherwise invisible until the final number is already wrong. A dropped coefficient, a sign lost in a substitution and a misapplied power rule all survive inspection and fail differentiation immediately. The example performs the check on each technique item, which also demonstrates to a scorer that the antiderivative was reasoned rather than recalled.
