Basic Engineering Mathematics & Modelling Solutions

A very simple project: Below is a link to a set of Maths questions: [login to view URL] You are then to record yourself explaining on how to to derive the solutions and what are the fundamentals used. The type of explanations will be something similar to the videos found in www.khanacademy.org. 1st Milestone: - Partial Differentials (Total, exact, line integrals, double) - Differential equation - Laplace - Fourier Series 2nd Milestone: - Dynamic systems, Modelling, Block Diagrams For the bidding, I need you to send me a youtube link of a 30s vid of you solving one of the topic question. Just 1 simple one will do. If I find your explanation is clear, I will award this project to you.
