My name is Alex Niedden and I am a math teacher based out of the suburbs of Chicago.
I use this channel to post the lessons from my classes as both a resource for my own personal students and all others looking for a little help in math. I have lessons for Geometry, Algebra 2, Statistics, Calculus 3, and Differential Equations. The lessons are generally organized into playlists for each unit.
While I teach a variety of math classes, my passion and area of expertise is statistics.

Hello, the teaching is fantastic. On 13:44, #5, how did you calculate or tell that the radius is 2?
You are a phenomenal educator
Why did the video suddenly blur out?
Which software did the textbook use to generate the diagram?
Very clear and great video. Thanks!
Ma'am i still didn't get it why is our goal to find partial of z with respect to y can you please explain. And how can we determine that our z is the dependent variable.
Hi, so how do we know when to find the intersection between x and y and when to just sketch the region D from the graph we graphed.
I can’t imagine you’re holding the pen like this and could write anything!
Thanks
So every time when we have to find gradient f = F we have to integrate right ?
5years ago and this is still helpful
how is 128 <0 in the table as it is a positive value and is greater than 0?
a،@
Thank you
your voice sound is so lovely Miss
❤
Don't sleep on this teacher. She's too good. 👌🏿
thank you so much
Great video, save from satan. Good 👍
❤❤❤
very nicely
Thanks 🙏🙏🙏🙏🙏
❤ thank you so much My teacher
In case 3 in lamda its have to be ( lamda <0) to be negative and use comlex
the noise of the pen is disturbing
Helo mam how do you see that the radius is 4 at 11:31
The radius is actually 1 and the height of the cylinder is 4. As you look at the figure, the "circular" part of the cylinder goes from x = -1 to x = 1, thus giving a diameter of 2 (radius of 1). The cylinder extends along the y-axis from y = -2 to y = 2, hence a height of 4. Hope this helps!
thank you for this. You just save my life.
why is x=x0; y=y0 a plane. I thought it's a line ? e.g: x = 3; y = 5 is a line parallel to Oz and can have any z value. thank you
x=# and y=# both represent lines in 2-space. Picture the line x=3 on the xy-plane. When we consider the equation x=3 in 3-space, that line then "goes up and down" with z forming a plane.
you are THE GOATTTTTT

Smn, answer please! At which grade do you study this?
I currently teach this class to high school seniors. This class is a dual credit, college-level course.
@@alexandraniedden5337 thanks
Thanks
Does this work if i have: Uxx+x=Ut 0<x<π U(0,t)=t U(π,t)=0 t>0 U(x,0)=(Cos(x))^(2) Because I tried using this video as a guide and my final Solution does not match the original P.D.E
Yes, it should work!
THANK YOU so much! <3
Thank you
bro thank you
thank you
This is the best teacher that I’ve ever seen. Period. Good job really 🫡
This is like the best time to upload this lol. My course has 16.2 to 16.5 and have finals tomorrow, been cramming your lectures for the past couple days
In 21:21, it should go from 0 to y not x.
Yes, you are correct. Thank you for the correction!
you are also like george green, most of students donot know about your work.Keep uploading lectures mam, they are very helpful.
These lectures are great, I have watched the whole chapter 14 and now speedrunning onto 15 and 16 as I have finals in two days
Could i get the notes madam?
Sure! Here is the draft: drive.google.com/file/d/1pt6SX9tjt2lAOfYityZxZyMuKXlYkFhC/view?usp=sharing There will be updates as I find mistakes :)
Waiting for 16.3 😍
My goal is to record 16.3 today. Check back later!
I have a question for these types of limits: after I try direct substitution and got an indeterminate form, do I just go straight into proving the limit DNE or first try limit rules first to see if I can get a limit value, and if that fails I prove the limit DNE?
First try limit rules. Ultimately if you get an indeterminate form, the limit most likely doesn't exist, but not always.
Living legend❤❤❤
What if u1 is something with du/dx in it?
Thank you my exam is after 5 days.
keep it up we like you ........from ethiopia
We appreciate you for being an awesome person ❤
