surface integral (KristaKingMath)

► My Vectors course: www.kristakingmath.com/vector...
In this video we'll learn how to evaluate a surface integral, where the surface is part of a plane that lies above an area in the xy-plane.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)
Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”
So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student-from basic middle school classes to advanced college calculus-figure out what’s going on, understand the important concepts, and pass their classes, once and for all.

Thank you! So clear!

[@racheltham8002]

Thank you so much for making this video, Krista! It helped me begin to understand surface integrals much more! :)

[@kristakingmath]

Oh good, I'm so glad it helped!

[@TwhiTEdits]

Saved once again this semester! Thanks!

[@kristakingmath]

:D

[@mcgarettsteve9077]

thorough explanation, i have to say ur the best Krista..appreciate the clear explanatory with an example and how relate the concepts within...thanks for the video and i have to say u do have a sweet voice..

Hi , what if I put dxdy instead of dydx ? Is possible? 😊🌹

[@jeanpierreistanbouli2225]

De absolute best. Calc 3 exam today

[@kristakingmath]

Hope the exam went great! :D

[@Ensign_Cthulhu]

Question - why have you chosen your dA as dy dx as opposed to dx dy? Given that the bounds are rectangular, it appears to me you could have chosen either.

[@kristakingmath]

You're right. Since the bounds are rectangular, you can easily do it either way. It's more standard to see dy dx than it is to see dx dy, since y is usually the dependent variable and x is the independent variable, but either way is completely fine.

[@Ensign_Cthulhu]

integralCALC Good explanation of why people put dy first, all else being equal. Thanks for your prompt and helpful reply. :)

[@basmaaslam2323]

Is this basically flux calculation?

[@senthur9308]

yes flux is calculated by this method

[@classicchessplayer7068]

did you take the example from patrickjmt?

[@kristakingmath]

No, but it wouldn't be unusual if we both made the same example! :)
