Following toggle tip provides clarification
Numerical Methods (Metric)
Learn, or revise, numerical integration, iterative solution of equations, fitting curves to data and numerical solution of differential equations.
Trapezium rule, Simpson's rule (A-level topics) and the Richardson extrapolation (not on lost A-level courses).
Iterative Solution of Equations
Fixed point iteration and Newton's method (on some A-level courses).
Interpolation using polynomials; least-squares regression (mostly First Year university topics).
Euler's method for the approximate solution of differential equations.
