THE ENGINEERING MATHEMATICS COLLECTION
Find the pattern.
Understand
the method.
From the first derivative to the bigger picture. Your Mathematics 3, Mathematics 5 and graph-plotting guides, brought together in a space made for learning.
= understanding + C
01 / YOUR BOOKSHELF
Your maths collection.
One place to begin.
The guides you shared earlier.
Choose a course and start reading.
Engineering
Mathematics 3.
Vector calculus, differential equations, Laplace and Fourier transforms, Fourier series and Z-transforms.
Engineering
Mathematics 5.
Read every original page and figure, search the guide, save bookmarks and keep notes alongside your working.
Maths 5.
Clearly organised.
Matrices, determinants, linear systems, eigenvalues, vectors and rank. Typed equations, worked examples and a revision formula sheet.
See the function.
Understand the graph.
Function graphs, symmetry, piecewise functions, periodic extensions and Fourier series. Includes redrawn figures and worked plots.
The original
graph notes.
Keep the handwritten explanations, sketches and calculations alongside the typed edition. Each original page is preserved in full.
Tutorial 2.
Every step explained.
Seven worked questions on inverse matrices, linear systems, diagonalisation, Bayes’ theorem, probability, Fourier series and inverse Z-transforms.
THE COMPLETE VISUAL LIBRARY
Your notes. Every original page.
Original figures, handwriting and worked calculations.
Read, zoom, search and save your place.
Diagrams are preserved on their original pages, including vector drawings and handwritten figures. Text search includes extracted text and OCR. Equations and handwriting may not be recognized correctly; use page thumbnails to find figures.
03 / MAKE THE MATHS MOVE
A curve.
A new perspective.
Explore y = A sin(kx). Change amplitude and frequency, then compare the curve with its derivative.
Illustrative practice tool. Angles are in radians.
y = sin(x)
04 / WORK IT OUT
Practise the method.
Small tools. Visible working.
Examples for independent revision.
ACTIVE RECALL
Identify the form.02
Choose the method.03

QUESTIONS
Is HNK Mathematics Lab free?
Yes. All 232 study pages, typed guides, worked solutions and practice tools are free, with no sign-up.
What topics are covered?
Engineering Mathematics 3 (vector calculus, differential equations, Laplace and Fourier transforms, Fourier series, Z-transforms) and Mathematics 5 (matrices, determinants, linear systems, eigenvalues, linear programming, probability and statistics).
Are there worked solutions?
Yes. Mathematics 5 Tutorial 2 has seven questions solved step by step, including inverse matrices, diagonalisation, Bayes' theorem, Fourier series and inverse Z-transforms.
Are my notes and bookmarks saved?
Notes, bookmarks and reading progress are saved in your own browser on your device, not on a server.
LEARNING, WITH A LITTLE WONDER
One page. One problem.
A little more understanding.
Your place, bookmarks and notes stay saved in this browser. More chapters can be added as your collection grows.
