parametric representation of the surface (KristaKingMath)

In this video we'll learn how to find the parametric representation of the surface, specifically the parametric representation of the part of a sphere that lies above a cone.

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?!”

Saving my grade as usual! You've helped me a ton through my calc journey!

You just explained to me a miracle in 15 minutes, I found nearly everything I was looking for in a single video. Thanks a lot Krista (the only difference is that my university is Australian, so they use a slightly different system, but the rest is fine!)

i love your hands on example! Great after reading and going to lecture. now i can do my homework.

While this is one of the solutions, the chapter parametric representation of the surface aims to teach us other ways to parametrize the surface. We already had a whole chapter of converting to spherical coordinates. I'd like to see it explain the other ways, e.g. x=x, y=y, z=√(4-x²-y²), for x²+y²≤2

What a great explanation, I really thank you for sharing your knowledge. God bless you. Of course I subscribe to your channel. Thank you.
