Calculus Tips & Tricks: Review

Calculus Tips and Tricks teaches the shortcuts, quick checks and common mistakes that make calculus faster and safer: 45 short pages on limits, derivatives, integrals and series.
Each calculus trick is shown in a worked example, then you try it yourself in practice questions with tap-to-reveal answers. It all works offline.

This is not another formula list. Each page answers a practical question: which technique should I use, how do I set this up, and how do I check my answer? Decision charts help you choose a method, and every topic warns about the calculus mistakes students make most often.

What you will learn

• Algebra and Trig Skills: factoring patterns, simplifying fractions and roots, completing the square, exponent and log rewrites, the trig identities you actually use, unit circle tricks
• Limits: which limit technique to use, factor, cancel or conjugate, squeeze and trig limits, dominant terms at infinity, L'Hôpital's rule: uses and pitfalls
• Derivatives: choosing the right rule, the chain rule layer by layer, avoiding the quotient rule, logarithmic differentiation, implicit differentiation steps, quick derivative checks, common derivative mistakes
• Applications of Derivatives: a related-rates recipe, an optimisation checklist, finding extrema fast, sign charts for curve sketching, reading a graph of f′, linear approximation checks
• Integrals: rewrite before you integrate, spotting a u-substitution, FTC shortcuts, integration by parts and choosing u, tabular (DI) integration, partial fractions and the cover-up method, trig integrals, which integration technique to use, symmetry shortcuts, setting up area between curves, checking by differentiating
• Series: choosing a convergence test, quick convergence checks, Taylor series to memorise, building new series from old ones
• Exam Strategy: managing your time, showing your work, calculator habits, checking units and signs, free-response habits, and the top 30 calculus mistakes
