I actually love the speed this guy was moving at. He was so concise it made learning this a pleasure. Great job and you helped a lot!!!

Why does a random dude who made a video on this 12 years ago teach this better than my professor

Yup. Triple integrals. I know how to do them but didn't get the chance to make a video series on them. Hopefully in the future.

Integrations are so awesome

Nope, sorry. Haven't dwelled in that area and probably won't anytime soon. I'm considering taking on Linear Algebra as used in Quantum Mechanics next. Thanks for your interest.

how did you get pi over 12? Don't you need to integrate cosine to sine then since 6 times 3 over pi is 2 pi then sin(2pi) is 0.

Great! Now I'm stuck at how (sin 3O)^2 equals (1-cos 6O)

Optimization? This is not an optimization problem which I assume uses differentiation. Or you mean parameterization?

With these problems, if I were asked to find the area of one petal,couldn't I find the area of the entire rose,then divide by however many petals there are? Say for r = 2cos(5theta). This will have 5 petals since n=odd. So can't I integrate from 0 to 2pi,then divide by final answer by 5? For some reason it doesn't work when n=odd. But when n=even I can use that method.

Thanks man! Im deeply grateful for your lessons, I was just desperately looking for some more :D I even learned more english here, cause i had to understand your fast speaking x) . Guess Im now ready for some more maths in the ETH =P

have you done anything on the uniqueness and existence, or exactness theorems?
@InitialDAmine15 жыл бұрын
nice effort i guess......... Just to let you know you made a little mistake written on the board while drawing O -> Sin(O) you wrotte instead Sin(3O). I m not going to explane how do it in a more simple way because maybe you didn't see or you polar fonction study wasn't as profound .
