Introduction to Course - Mathematics for Electrical Engineers Modern science and engineering requires high levels of qualitative logic before the act of precise problem formulation can occur. Thus, much is known about a physio electrical problem beforehand, derived from experience or experiment (i.e., empiricism). Most often, a theory evolves only after detailed observation of an event. Thus, the first step in problem formulation is necessarily qualitative. The second step is the bringing together of all applicable physical and electrical information, imperial laws, and rate expressions. At this point, the engineer must make a series of critical decisions about the conversion of mental images to symbols, and at the same time, how detailed Page 1 of 9
the model of a system must be. Here, one must classify the real purposes of the modelling effort. Is the model to be used only for explaining trends in the operation of an existing piece of equipment? Is the model to be used for predictive or design purposes? The scope and depth of these early decisions will determine the ultimate complexity of the final mathematical description. The third step requires the setting down of appropriate methods to solve the model. In the limit, as the differential elements shrink, then differential equations arise naturally. Next, the imposed conditions must be addressed, and this aspect must be treated with considerable circumspection. When the problem is fully posed in quantitative terms, an appropriate mathematical solution method is sought out, which finally relates dependent (responding) variables to one or more independent (changing) variables. The final result may be an elementary mathematical formula, or a numerical solution portrayed as an array of numbers. 1.2 Course objective: Calculus aims at the study of advanced modules like Fourier Series, Laplace Transformation, Vector Calculus, and Complex Analysis Fourier Series which is useful to do Network Analysis in Electrical Engineering Differential Equations and its applications to Electric Circuit Analysis 2.

Teaching-learning methodology 1. Lectures: Primarily Chalk and Black board will be used to conduct the course. However, where required, Power Point Presentations (PPTs), Video Lectures, Simulations / Animations etc. will be used to enhance the teaching-learning process. 2. Tutorial: Emphasis will be on one to one interaction with students for clearing their doubts and problem solving. 9. Active learning techniques Active learning is a method of learning in which students are actively or experientially involved in the learning process. Following active learning techniques will be adopted for the course. Flipped Class-room (Topics mentioned in self - study))- Flipped classroom is an instructional strategy and a type of blended learning that reverses the traditional learning environment by delivering instructional content, often online, outside of the classroom. It moves activities, including those that may have traditionally been considered homework, into the classroom. In a flipped classroom, students watch online lectures, refer the books or online lecture notes, or carry out derivation at home and present the concepts in the classroom with the guidance of a mentor. Page 8 of 9
Muddiest Point- At the end of each session the students are asked share any topic which is not or difficult to understood. For such topics a discussion may be done in the class. Surprise test in the form of Quiz- To ensure the understanding of the students during the class, the surprise test in the form of quiz may be given at any time during the class. 10. Course Material Following course material is uploaded on the course website: ma06appliedmaths.wordpress.com PPTs, Notes, Handouts Tutorials Question bank Useful links (Applications) 11. Course Learning Outcome Attainment Following means will be used to assess attainment of course learning outcomes. Use of formal evaluation components of continuous evaluation, tutorials, laboratory work, semester end examination Informal feedback during course conduction 12. Academic Integrity Statement Students are expected to carry out assigned work under Continuous Evaluation (CE) component and LPW component independently. Copying in any form is not acceptable and will invite strict disciplinary action. Evaluation of corresponding component will be affected proportionately in such cases. Turnitin software will be used to check plagiarism wherever applicable. Academic integrity is expected from students in all components of course assessment. Page 9 of 9
