Ключевые идеи главы в понятной последовательности перед практикой.

Change and approximation

Calculus studies how a quantity changes and how small changes accumulate. Graphical interpretation should accompany the notation.

Conditions before the rule

Check domain, continuity, or differentiability where required. A correct rule cannot be applied mechanically outside its conditions.

Interpret the result

A derivative represents local rate of change and a definite integral represents net accumulation. Always reconnect the result to the original problem.

AA: proof, exact algebra, analytical calculus, trigonometric identities

Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.

Worked rate-of-change example

For f(x) = x³ - 2x, find the derivative and the gradient at x = 6.

1Differentiate term by term: f'(x) = 3x² - 2.
2Substitute x = 6.
3Interpret the value as the tangent gradient.

f'(x) = 3x² - 2, f'(6) = 106

Reasoning example

Before calculating, explain the key idea from “AA: proof, exact algebra, analytical calculus, trigonometric identities” and which conditions must be checked.

1Define the idea in one clear sentence.
2Connect it to a representation, law, or formula.
3State a restriction, unit, or final check that makes the solution valid.

The answer should show not only which rule is used for “AA: proof, exact algebra, analytical calculus, trigonometric identities”, but also why it is valid here.
