The boundaries refer to a specific variable. So, initially I was integrating with respect to x from [0,2]. However, we ended up integrating with respect to u later in the problem. Since u = 2x, if x is [0,2], that means u is [0,4]. Hope that helps.
Hi, thank you so much for various examples with detailed examples. The 3D modelling using Geogebra was so helpful as well. What a great skill of Geogebra! I have two things to ask you if you dont’t mind. ;) 1.How did you colour the cross section of semicircle? Im building a model for school project and Mine just look like a shell. Not like volume as yours. Polygon shapes are automatically filled and there is an option for fill in setting but there is none for a circle , semicircle for some reason. :( 2. Could u teach me how to set up a slider for n (numbers of a shape)? I searched internet but I found only one video of using uppersum command. If you could teach me, or make another youtube video to show how to do it, it will be super helpful for many viewers, dont even need to mention of me! Or if you too busy to make a video, could you tell me the link that would answer my two questions? Thank you so much! This cross section integration is really fun to learn :D
Hi SSS K, I'm sorry for the late response. I wasn't seeing the comments in my email, and I was unaware of them until just now. I'm not sure I remember off the top of my head how I did that. If you are still interested reply to this and I'll try to find the original file for you. As for the slider to create shapes, I do that using the Sequence command in Geogebra. You can google it. It allows you to essentially create a for loop where you can have it do something (like create a shape) for a certain number of repetitions. This is how I create the repeated shapes with the slider.
greetings from turkey istanbul
Hello from New York in the United States 👋
This is really good! I'll share with my students.
10/10 easy to understand even for me who struggle with math
That’s terrific, I’m glad you found it helpful 😀
How did you make it so you had the graphing and 3 d screen side by side?
Hey Steven- thanks for watching! I’m using GeoGebra Classic, and you can toggle all the windows on and off...
@@RealMikeDobbs I don't understand. I am a tyro in classic

Why did the boundaries change?
The boundaries refer to a specific variable. So, initially I was integrating with respect to x from [0,2]. However, we ended up integrating with respect to u later in the problem. Since u = 2x, if x is [0,2], that means u is [0,4]. Hope that helps.
excellent video
Thank you 😀
Thannnnkkk yoooouuui
You're very welcome 😄
thank you!
You are very welcome 😀

Here's a Google Drive link for the file. Hopefully this helps you: drive.google.com/file/d/1M3RoxWK-IxtZpZayORz7WU09w0HnUyu6/view?usp=sharing
