Engineering Mathematics
The most beautiful formula in mathematics is $$e^{j\pi } + 1 = 0 $$ This is because it relates the numbers $$e$$, $$j$$, $$\pi$$, 0 and 1. What is your favourite formula? We use j instead of i because engineers use i to denote current in electrical circuits. Whenever engineers are informed that they need to do mathematics as part of their undergraduate programme, they often make the point what use is all this maths for engineering. Where is the maths in engineering? An excellent source would be the textbook "Engineering Mathematics Through Applications". It answers the following questions: How is differentiation used in aerodynamics? How does trigonometry help in communications? What is the likelihood of you winning the lottery? Where do engineers use complex numbers?
