EMT1201 Engineering Mathematics II introduced Differential Equation and Solution Techniques for ODEs with Exact Solutions in terms of Elementary Functions (Algebraic, Trigonometric, Exponential, Logarithmic and Hyperbolic Functions) and EMT2101 Engineering Mathematics III Introduced the Power Series Solutions to ODEs, it was appreciated that the analysis of Engineering Systems containing lumped parameters often leads to ODEs in which time is the only independent variable
