WHY DO ENGINEERS NEED MATHEMATICS?

In mathematics classes across the world, one of the most common things you will hear students mumble under their breaths (while they copy down yet another algebra problem) is: When are we ever going to need this in real life?
But there’s a special branch of mathematics that deals with problems ‘in real life’. This branch is called applied mathematics, and if you happen to become an engineer one day, you will find yourself using this kind of mathematics on a daily basis.
Applied mathematics is often used to solve complex practical problems. And it is when used by engineers that this kind of mathematics brings about the most invaluable real world solutions to our problems: How do we make a 300-ton aircraft fly through the sky? How do we build a bridge that can cross a 1km river? How do we stop skyscrapers from collapsing during an earthquake?
Mathematics really is the cornerstone of all engineering. Without it, bridges would collapse under tension, light bulbs might blow up each time you flip a switch in your house, and your car brakes would only work some of the time.
Given that many students encounter some mathematics during their studies, the following 5 tips have been created to help you form a better understanding of mathematics.
Confidence
Many students find mathematics difficult because they “believe” they cannot solve the exercises or understand the material, even before they begin. Approach mathematics and mathematical work with confidence and a positive attitude – you can do it!
Time management
If you are stuck on a mathematical problem for too long then move on to the next one and come back to it later. You may be surprised at what revelations a break and a fresh viewpoint can provide.
Start with special cases and simple examples
Many students learn a new topic most effectively by engaging with concrete examples as opposed to examining general theories. For example, if you are presented with an abstract mathematical formula then try to construct some simple, special cases or look at some applied examples involving the formula. These simpler and contextualized situations will provide the basis for you to understand the more general or abstract setting.
A picture paints a thousand words
Much of mathematics involves very precise notation designed to convey deep and carefully crafted ideas. In some cases a simple picture, sketch or diagram can easily express the main idea in a powerful, geometrical way. If a mathematical statement seems like abstract squiggles on the page then consider, or ask, if there is a diagram to illuminate the big picture.
Mathematics is not a spectator sport
Actively watching your teacher solve mathematical problems does have educational benefits, but the most important advice is that you will learn mathematics by doing mathematics! How?! By having a positive attitude, good time management, by examining contextualized examples and starting with special cases. Furthermore, by employing insightful pictures and simply doing mathematics.
