AQA A-Level Mathematics

Flashcards for AQA A-level Mathematics (7357), split into pure mathematics, statistics and mechanics and then by topic in the specification's order. A card's extra note says whether a formula is given in the exam's formulae booklet or has to be recalled.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.

Some of its cards

• In a histogram, what does the area of each bar represent?

  The frequency of the class it represents
• What is the compound angle formula for $\sin(A+B)$?

  $\sin A\cos B + \cos A\sin B$
• What is a population, in statistics?

  The whole set of items or individuals that a study is interested in
• What does the Fundamental Theorem of Calculus state, in outline?

  Integration and differentiation are inverse processes, so $\int f'(x)\,dx = f(x) + c$
• What is the vertical asymptote of the graph $y = \frac{a}{x}$?

  $x = 0$ (the $y$-axis)
• What form does the partial fraction decomposition of $\frac{5x+1}{(x-1)(x+2)}$ take?

  $\frac{A}{x-1} + \frac{B}{x+2}$, for constants $A$ and $B$
• What does a fractional index $a^{1/n}$ mean?

  $\sqrt[n]{a}$, the $n$th root of $a$
• How is a vector in two dimensions written in component form?

  $\begin{pmatrix}x\\y\end{pmatrix}$ or $xi + yj$
• What is the period of $y = \sin x$ and $y = \cos x$, in radians?

  $2\pi$
• What is proof by deduction?

  Starting from known facts, definitions or assumptions and reasoning through a logical chain of steps to reach the conclusion
