Why must a constant of integration +c+c+c be added to indefinite integrals?
Constants have a derivative of zero, so they are lost during integration and must be recovered.
Constants have a derivative of zero, so they are lost during differentiation and must be recovered.
Constants have a derivative equal to themselves, so they are lost during differentiation and must be recovered.
Constants have a derivative of one, so they are lost during differentiation and must be recovered.
Flashcards for Edexcel A Level Maths Integration, covering the key formulae, methods and definitions you need to recall for Paper 1, Paper 2 and Paper 3. 21 cards drawn from 11.1 Integrating Standard Functions, 11.2 Integrating f(ax + b), 11.3 Using Trigonometric Identities, 11.4 Reverse Chain Rule, 11.5 Integration by Substitution, 11.6 Integration by Parts, 11.7 Partial Fractions, 11.8 Finding Areas, 11.9 The Trapezium Rule, 11.10 Solving Differential Equations, and 11.11 Modelling with Differential Equations, matched to the Edexcel A Level Maths (9MA0) specification. Recall questions account for roughly 50% of marks at A Level Maths, so these target the marks you can secure before the paper starts.
