What is a surface integral? (part 1) Chris Tisdell UNSW

This lecture gently introduces the idea of a "surface integral" and illustrates how to integral functions over surfaces. The idea is a generalization of double integrals in the plane.

The concept of surface integral has a number of important applications such as caculating surface area. In addition, surface integrals find use when calculating the mass of a surface like a cone or bowl.

A number of examples are presented to illustrate the ideas.

Such concepts are seen in 2nd-year university mathematics courses.

How many lectures are there altogether? i've sen up tp 14... that all?

[UNSWelearning]

@speckofdust21 There are 14 on vector calculus (plus one on Fourier series and PDE). Enjoy!

[Arycke]

excellent lecture

[UNSWelearning]

@Arycke A very late reply of thanks!

[MrPEDOCTOR]

thanks for the video

[UNSWelearning]

@Iceiam Thanks for pointing this out!

@d0nunit You equate the equation for the sphere and the plane.. and you get x^2+y^2+(2)^2=9

which gives you wat you want!

you just lost me how you got 5 :(
