So a while back, I said I am going to start writing "Colloquial books" about all of the courses I took as I relearn all of the stuff in my and other Engineering Branches (minus the grade-gun pointed at my head). One of the first courses are of course Calculus. I skimmed through some of these video lectures, I wonder if I even should write books for this. Or simply href. Thank you for the share. Will be of great help to me come summer.
