Thank you Knewzi, I really appreciate it. Let me know if I could help you with any math problems. JaberTime

@@19917119 I'm watching the calculus 3 playlist you have created just to quickly review the materials for an exam. Each video is packed with good amount of practices.

[@19917119]

@@knewzi3152 That is good to hear. I do have some time to make more. So if you need a specific topic of Calculus 3, just let me know and I will add a video with excamples to help. I like the idea of writing my notes ahead of time so that I can have less recording time and a shorter video than recorinding on a white board. I belive that saving the time and going over hand written organized notes will be a postive thing to do. That is why I call my videos: Lecture Videos with simplified Examples. JaberTime

[@irving9509]

Dang I actually like your video, greatly detailed and color coordination helped keep thoughts organized.

Thank you so much, you have helped me to understand for a vector function very well.

Thank you so so much for this video. I was finally able to understand all! It was impressive. Thank you ^^

[@19917119]

You are welcome! Let me know if there is anything I can do to help, please. If there is a topic or a problem that I can help you with, let me know and give me a few days and I will make a video for it. JaberTime

Thankyou Sir !!

[@arunkumarkrishnamoorthy88]

when t=0 ,then x=1,y=0,fine when t=360 what about z???will the z ( i mean height) for one cycle magnitude reach 360?

[@19917119]

T is in radians, not degrees. If you are referring to the last example " the Helix" , then the height will keep increasing in radians. If you are not referring to the last example, let me know which example and I will explain more.

One cool way to think about it is the velocity vector function of a rider on a rollercoaster

[@19917119]

I like it. I will be the rider.

Thank you so muchh

[@Uknon78]

Thanks, without parameter, can we sketch space curve? Like this eq : ŕ=x^2 ī + 2y j + 5z k

[@19917119]

Hi Rahul, Type that in www.geogebra.org/3d GeoGebra.org is free online software. Click on 3D Calculator and type r= x^2 I+ 2y j + 5z k. Then with the mouse pointer to the graph, click and hold and move the graph. Let me know if that works for you, please. JaberTime

[@19917119]

Hi Rahul, If you want to sketch a space curve, do the following: Try to type the following in GeoGebra: www.geogebra.org/3d Curve(t^2, 2t, 5t, t, 0, 7) It will show you the curve with the parameter t from 0 to 7. You can change 0 to 7, of course to your own numbers. JaberTime

[@19917119]

Hi Rahul, Let me know if you still need any help, please. JaberTime

[@Uknon78]

Thanks sir , i solved that

[@aylora7033]

@@Uknon78 wait, if there is no t or a parameter, it doesnt make sense. the components u wrote are functions; there is an independent variable. if there is no parameter then it is only a directional vector, helps to fix a one specific direction for a point to follow like in straight lines vector equation. and the components are regular constant numbers. for a curve the direction is not constant

[@madhusankawijerathne8435]

Thx sir

[@19917119]

Hi Madhusanka, I will add a short video by next week on this topic using GeoGebra. Also, I will post a link to the actual GeoGebra Example that I am going to use so you can see all the steps and you can move the sliders yourself and change the view within GeoGebra. I am sure that you will like it. JaberTime
