Orthogonal Projections - Scalar and Vector Projections - Example 2

[colechapman]

Ok but how do you do a projection orthogonal to a vector. This is just normal projection

[garen]

why is the denominator squared? thanks

needed this for my vector calculus last semester but hopefully i shall pass it thanks to your other videos
much obliged mate :)

Thank you patrick. One question, what is the component vector of b along a mean?

[izelkay]

Thank you for this. This is part of what we're doing in class right now, haha.

I understand how to use the formula, but what's the maths behind this one? How did they find out this ratio was a scalar for the orthogonal vector of the projected vector?

I passed my last math exam on university, with your help and some others, thank u very very much!

This was really helpful, thankyou so much!
