What you will learn

  • Important Formulae and Procedures

  • Derivations

  • Engineering relevance of critical concepts

  • Model Question Paper Problems

This course is an inaugural offer with 30 days validity, ensuring you can grasp these foundational concepts within a focused timeframe. Elevate your mathematical prowess with our online engineering mathematics course tailored for Mechanical Engineering students at Visvesvaraya Technological University (Course Code: 21MAT11). Uncover the essentials as you journey through Calculus, Series Expansion, Multivariable Calculus, Ordinary Differential Equations, Higher Order ODEs, and Linear Algebra in Modules 1 to 5 respectively. Seamlessly blending theory and application, this course empowers you with the mathematical tools crucial for excelling in Mechanical Engineering. M1 for mechanical and civil engineers incepts with polar coordinates for general situations in mechanics and physics. Derivative and successive derivatives are used for tailor series. Further there is a perfect transition from single variable to multivariable calculus, hence total derivative and jacobian which are powerfully used in mechanical engineering for simulation and optimization. The basic math modelling is via higher order ordinary discussion of differential equations. Finally Linear algebra with emphasis on rank, eigenvalues and eigen vectors makes it a perfect base curriculum be it stress or vibration analysis or fluid or thermal analysis.
