General maths

Vector fields intuitively explained. Note: the first few pages talk about how there's a plan about how vector calculus is going to be taught. You can ignore those, as I won't be uploading the other notes laid out in the plan. The two red and bold sentences on page 2, however, should not be ignored, and you should think of them every time you think of vector calculus. Note 2: as Stuvia does not allow uploads of videos or gifs, the quality of the presentation of the note will be damaged, as t...

Upper and lower limits of multiple integrals in various geometries (3D) explained. This is not a course-specific content. Exercises come from James Stewart Calculus, 8th Edition.

Upper and lower limit of multiple integrals for various geometries (2D) explained. This is not a course-specific content.

An intuitive and graphical way to understand how the least squares method is used for curve-fitting.

A guide for you to parametrize surfaces in 3D space. Prerequisite knowledge = equation of planes. Unfortunately Stuvia does not allow uploads of videos or gifs, so you have to use your imagination in places where this note says "an animation is provided". For this reason this note is priced lower than my usual price. You are invited to create these animations on your own in Geogebra. They are not that hard! This is not a course-specific content.
