Students will be expected to know and use the Fundamental Theorem of Calculus, evaluate definite integrals; use a definite integral to find the area under a curve and the area between two curves and understand and use integration as the limit of a sum. The will also be expected to be able to evaluate the analytical solution of simple first order differential equations with separable variables, including finding particular solutions and then interpret the solution of a differential equation in the context of solving a problem, including identifying limitations of the solution; this includes links to kinematics.

• ##### AQA 7357: Year 12 & 13 Numerical methods

Numerical Methods involves uses methods such as Iterative, Recurrence, Newton-Raphson and Trapezium in order to solve problems in context

• ##### AQA 7357: Year 12 & 13 Vectors

Students will be expected to be able to calculate the magnitude and direction of a vector and convert between component form and magnitude/direction form. They will also be expected to understand and use position vectors; calculate the distance between two points represented by position vectors and use vectors to solve problems in pure mathematics and in context, including forces and kinematics.

• ##### AQA 7357: Year 12 & 13 Quantities and units in mechanics

Students will be expected to understand and use fundamental quantities and units in the SI system: length, time, mass, as well as understand and use derived quantities and units such as velocity, acceleration, force, weight and moment.

• ##### AQA 7357: Year 12 & 13 Kinematics

Students will be expected to understand, use and interpret graphs in kinematics for motion in a straight line: displacement against time and interpretation of gradient; velocity against time and interpretation of gradient and area under the graph. They will also be expected to use calculus in kinematics for motion in a straight line and extend this to 2 dimensions using vectors.

• ##### AQA 7357: Year 12 & 13 Forces and Newton’s laws

Students will be expected to understand and use Newton’s laws and their application to problems involving smooth pulleys and connected particles.  They will also be expected to resolve forces in 2 dimensions; find the equilibrium of a particle under coplanar forces, understand and use addition of forces; resultant forces and dynamics for motion in a plane. In addition, they will understand and use the F ≤ ߤR model for the motion of a body on a rough surface and limiting friction and statics.

• ##### AQA 7357: Year 12 & 13 Moments

Students will be expected to understand and use moments in simple static contexts.

• ##### AQA 7357: Year 12 & 13 Statistical sampling

Students will be expected to understand and use the terms ‘population’ and ‘sample’, use samples to make informal inferences about the population, understand and use sampling techniques, including simple random sampling and opportunity sampling and select or critique sampling techniques in the context of solving a statistical problem, including understanding that different samples can lead to different conclusions about the population.

• ##### AQA 7357: Year 12 & 13 Data presentation and interpretation

Students will be expected to interpret measures of central tendency and variation, extending to standard deviation, be able to calculate standard deviation, including from summary statistics and recognise and interpret possible outliers in data sets and statistical diagrams. They will also be able to select or critique data presentation techniques in the context of a statistical problem and be able to clean data, including dealing with missing data, errors and outliers.

• ##### AQA 7357: Year 12 & 13 Probability

Students will be expected to be able to model with probability, including critiquing assumptions made and the likely effect of more realistic assumptions.

• ##### AQA 7357: Year 12 & 13 Statistical distributions

Students will be able to understand and use the Normal distribution as a model, find probabilities using the Normal distribution and the link to histograms, mean, standard deviation, points of inflection and the binomial distribution. They will be able to select an appropriate probability distribution for a context, with appropriate reasoning, including recognising when the binomial or Normal model may not be appropriate.
