Algebraic and trigonometric skills

Geometric skills

  • Geometric vectors

    Vectors describe movement with both direction and magnitude. They can be added or subtracted to produce resultant vectors. The scalar product can be used to find the angle between vectors.

  • Working with vectors

    Evaluate scalar product and determine the angle between two vectors

Calculus skills

  • Differentiation

    Differentiation of algebraic and trigonometric expressions can be used for calculating rates of change, stationary points and their nature, or the gradient and equation of a tangent to a curve.

  • Integration

    Integration is the inverse of differentiation of algebraic and trigonometric expressions involving brackets and powers. This can solve differential equations and evaluate definite integrals.

  • Applying differential calculus

    Optimization is used to find the greatest/least value(s) a function can take. This can involve creating the expression first. Also find the rate of change by differentiating then substituting.

  • Applying integral calculus

    The area above and below the x axis and the area between two curves is found by integrating, then evaluating from the limits of integration. Integration is also used to solve differential equations.

Algebraic and geometric skills

  • Rectilinear shapes

    Find the gradient, equations and intersections of medians, altitudes and perpendicular bisectors using our knowledge of the mid-point as well as parallel and perpendicular lines.

  • Circles and graphs

    The equation of a circle can be found using the centre and radius. The discriminant can determine the nature of intersections between two circles or a circle and a line to prove for tangency.

  • Sequences

    A recurrence relation is a sequence that gives you a connection between two consecutive terms. This connection can be used to find next/previous terms, missing coefficients and its limit.
