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.

The way I think about the second one is as follows: To start, I obviously look at the equation, and I see it has two variables. At first, I think about this in a two-dimensional space, in this case the yz-plane (I know we are graphing in 3 dimensions, but I'll get to that later). So I graph the equation there and see that it is a downward-facing parabola. Now, because we are graphing in 3-space and because I don't see an "x" in the equation, I think of it as "x" can be anything because no matter what "x" is, the equation essentially never shows any change except a shift along the x-axis. To me, this represents the "main" (I just call it that) parabola shape in the yz-plane extending along the x-axis to create the resulting figure that was drawn in the video.

@vaibhavnayel 10 лет назад
Hey, just a passing remark: Just because the equation doesn't include an x-term doesn't mean the surface will never touch the x axis. For example, z= y^2 always touched the x axis for every point whose y and z coordinates are both 0.

I noticed that some comments are really old , how old are you now if you don't mind me asking ? Edit: btw what's the purpose of traces , I'm not sure if it's a stupid question , I'm still early into this work and I started before the class so it's a bit difficult understanding concepts from just books
