Success in Maths for (Beginning) Engineering

Engineers require a sound knowledge of mathematics.

To assist you if you have had bad experiences at school, not enough exposure to mathematics or the exposure was a number of years ago we have developed a series of videos.

Please complete the online readiness test for ENM1500 to self assess if you need to work through the videos. These videos are based on the appendices in the ENM1500 materials.

To view files click on the topic you wish to refresh and choose the MP4 or iPad option. A copy of presentation is available for you to download (Print Handout).
