Dr. Trefor, you explain the content very very well. I am currently in Calc 3 with good grades and understanding. Without your videos, it would have been VERY VERY difficult for me to understand what I learn in lectures. You explain not just the what but the WHY, and that has helped me so much!! The visualization that you use has been SOOO much helpful too. And you posted the whole course!!! In 10 to 20 minutes, you explain things way better than what I get from attending a 1 hour lecture. Thank you very much!!! God bless you

I’ve got to say your videos are great if I were to make one suggestion it would be to slow down your speech a little bit you seem very excited which is awesome but for a laid-back dude like me it was a bit overwhelming how overtly excited you are. That said I’m looking to get into vector calculus and linear algebra and I’m wondering where a good starting point is because after watching your videos I realize there’s a lot of fundamental theoretical knowledge that’s required and so where would a good base be because like you I’m very ambitious but sometimes I have to measure my ambition with a modicum of patience. Keep making these amazing videos and I hope you read the comments. A convivial Thursday to you!

@carultch
Жыл бұрын
@@chyldstudios Field in this context means function of space. Like a temperature map, gives temperatures at each geographical location. A temperature map is a representation of a temperature field, which is an example of a scalar field. A scalar function of each point in space. Another example of a scalar field, would be an elevation map. Elevation is the scalar, while the x-position and y-position is the point in space as the input to this scalar function. A vector field specifically, is a function of space that gives you a vector quantity at each point, rather than a scalar function. The most common examples you see of applications of vector fields, are velocity vector fields of fluid flow, and force fields, like the electric and magnetic fields. Force fields give instructions to a body sensitive to the force field, for what force it should experience at each location in space, based on the applicable property of matter (e.g. electric charge).

Yes (with the condition that the domain and codomain are both the same dimension). But the main point of vector calc isn't that the fundamental object is all that unfamiliar, instead it is that it has a lot of physical significance and we can do all sorts of physical things with it like flux and so forth. Haha one of these days I may upgrade to the tensor view which is a nice generalization
