Thanks for the second method. It's useful to avoid dividing by 0.
Which drawing program is that? It's neat that drawn lines are automatically straightened.
I used an app on Samsung laptop called Noteshelf. Thank you for the comment!!
Congrats on 2k subscribers!
Thank you! I am working toward 3k now 😁
I prefer second method and thanks I like your video is helpful 👏
Thank you! Please help share this video with others 😁👍
Thanks for the approach one
Thank you for your comment! Please share my video with others 😁
I like your teaching
Thank you! Please help me share the video with others 👍😁
For approach number 2, how do we work out a vector in 2 dimensions?
If a vector lies in the xy-plane, for example, v = (1, 3), then we can choose z = 0. That is, (1, 3, 0) in the space.
Thanks that makes sense
thanks sir g
You are welcome! Definitely help me share the videos with others 😁
Why is it that you choose 1,1,2 in the first approach
I chose that because the numbers are easy. We can choose other numbers since there are infinitely many vectors perpendicular to .
Isn't there a way to solve it properly without picking any random no.
Both approaches are proper ways to solve this problem. In fact, there is no problem with picking random numbers since the answer is not unique for this question.
cant abc just equal 0?
But the zero vector is not a unit vector.
@@GlassofNumbers oh okok thanks for the response🙏
