Solve f(x) = x² − 2 = 0 with f′(x) = 2x, starting at x₀ = 1, using xₙ₊₁ = xₙ − f(xₙ) ÷ f′(xₙ).
| n | xₙ | f(xₙ) | xₙ₊₁ |
|---|---|---|---|
| 0 | 1 | −1 | 1 − (−1 ÷ 2) = 1.5 |
| 1 | 1.5 | 0.25 | 1.5 − 0.25 ÷ 3 ≈ 1.416667 |
| 2 | 1.416667 | 0.006944 | 1.416667 − 0.006944 ÷ 2.833333 ≈ 1.414216 |
The true value is √2 ≈ 1.414214. The number of correct digits roughly doubles each step, which shows quadratic convergence.
Two standard problems.
| Question | Working | Answer |
|---|---|---|
| ∫₀¹ x² dx by the trapezoidal rule, h = 0.5 | (0.5 ÷ 2)[0 + 2(0.25) + 1] | 0.375 |
| Same integral by Simpson's 1/3 rule | (0.5 ÷ 3)[0 + 4(0.25) + 1] | 0.3333 (exact: 1/3) |
| y′ = y, y(0) = 1, Euler with h = 0.1: y(0.1) | 1 + 0.1 × 1 | 1.1 |
| y(0.2) | 1.1 + 0.1 × 1.1 | 1.21 (exact: e^0.2 ≈ 1.2214) |
Simpson's rule is exact for polynomials up to degree 3, which is why it gives 1/3 exactly here.

Most lost marks come from stopping iterations too early and not discussing error.
| Mark-loser | What to do instead |
|---|---|
| No stopping criterion | State the tolerance or number of iterations |
| Too few decimal places | Carry extra digits and round only at the end |
| Simpson's rule with an odd number of strips | Use an even number of intervals |
| Newton–Raphson from a poor starting point | Choose x₀ near the root and check f′(x₀) ≠ 0 |
| No error comparison | Compare with the exact value or estimate the error |
| Uncommented code | Comment your MATLAB or Python code |
Numerical methods is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Exams | Accurate iterations and formulas with tables |
| Problem sets | Complete working and error discussion |
| Coding assignments | Correct, tested code with output |
| Lab reports | Methods compared for accuracy and speed |
| Projects | Applying methods to engineering problems |
Numerical methods courses use these tools.
| Tool | What it is used for |
|---|---|
| MATLAB | Implementing and testing methods |
| Python with NumPy and SciPy | Scientific computing |
| Excel | Iteration tables |
| Scientific calculator | Exam calculations |
| Wolfram Alpha | Checking exact values |
Numerical methods is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where numerical methods is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | A-Level Further Maths and engineering mathematics modules | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | Few citations; Harvard or numbered if required |
| United States | Numerical analysis courses in maths and engineering | Letter grades A–F and a 4.0 GPA scale | Few citations; APA or numbered if required |
| Australia | Numerical methods units | HD, D, C, P at university; ATAR for school leavers | Harvard if required |
| Canada | Numerical analysis courses | Letter grades or percentages; GPA scales vary by province and university | APA or numbered if required |
| India | B.Tech/BE numerical methods (often with Engineering Mathematics III or IV) and BSc mathematics | Board exam percentages; university CGPA, often on a 10-point scale | Few citations; as your university specifies |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of numerical methods help depends on the number of problems, any coding and your deadline. A short iteration problem costs less than a coding project. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Techniques for finding approximate solutions to mathematical problems that are hard or impossible to solve exactly.
It repeatedly halves an interval where the function changes sign, keeping the half that contains the root.
Near a simple root its error is roughly squared each step (quadratic convergence), so correct digits about double per iteration.
When f′(x) is zero or near zero, or when the starting value is far from the root.
Round-off error comes from limited precision; truncation error comes from approximating an infinite process.
The smallest number that, added to 1, gives a result different from 1 in floating-point arithmetic.
A method that approximates an integral by summing trapezium areas under the curve.
It fits parabolas instead of straight lines, so its error is much smaller for smooth functions.
A method for finding the polynomial that passes through a given set of points.
Gauss–Seidel uses updated values as soon as they are computed, so it usually converges faster.
