Incorrect
I would like to suggest that this solution is incorrect.
The formula for projection is not correct.
My fellow classmates have also suggested this as well.
Hi, how did you learn the formula for vector projection in class? Can you state more specifically what is wrong here? Is it just the denominator, which should be instead of Failed to parse (syntax error): {\displaystyle |\mathbf{u}| = \sqrt{5} } ?
