Patrick J

Patrick J, known online as PatrickJMT, has been making free maths videos since 2007. His channel is one of the longest running maths help resources on YouTube.

Each video works through a problem on screen, one step at a time. The range is wide: algebra, trigonometry, calculus, limits, statistics and mechanics. Recent uploads focus on hypothesis testing and confidence intervals. The style is plain and patient, with no distractions, which makes the videos useful when stuck on homework or revising for exams.

Some highlights include:

A worked example on the conical pendulum shows how to resolve forces and find the speed of a swinging mass.

A loop-the-loop problem works out the minimum speed needed to stay on the track at the top.

Two connected blocks on a slope with friction are analysed, a classic mechanics question for exams.

The channel has around 1.4 million subscribers.

These mechanics and statistics problems are the same kind of maths that engineering students use in their first year. Forces on slopes and circular motion underpin mechanical and civil engineering. Statistics matters in quality control and testing. The channel is a reliable support for A level maths, further maths and physics. Because the archive is so large, there is usually a video on almost any topic a student gets stuck on. It is a practical tool rather than entertainment, and it builds the confidence with numbers that every engineering course expects from day one.
