CS Degree Day 12

This is turning out to be way more difficult than what I anticipated. While Calculus I was challenging in an exciting manner, Calculus II is inexplicably convoluted. It seems all fine when attending lectures and solving the in-class problems. But as soon as I look at problem sets, the house of understanding crumbles down. The solution consists of statements that are just thrown in as fact with no prior mention or context. I felt that I was weak on basics, so I picked up “Introduction to Linear Algebra”. This did help me understand some of the key concepts with better intuition, but as soon I went to apply the concepts to psets, there was another dissapointment. Both treat linear equations from very different geometric perspective. For MIT course, series of linear equations are like planes. The place of intersection of these planes is the solution. For the book, linear equations are like addition of components of vector. The scalar multiplier of each component such that addition of vectors for the required vector is the solution. And “Linear Algebra Done Right” describes these concepts in yet another manner. And 3blue1brown has yet another interpretation on it. There is chasm between even the fundamental explanation of the topic.

What I did today?

Attended three lectures & did assingments

• Square system and plane equations
• Parametric Equations
• Velocity & Acceleration
