Question

already solved. thanks anyways

Answer 1

Two vectors are orthogonal if their dot product is 0:
\[v\cdot a=\left(b-\frac{a\cdot b}{a^2}a\right)\cdot a\]
I suspect there are some missing symbols...
\[\frac{a\cdot b}{a^2}a\]
should be a vector, but the notation doesn't make sense as is. Did you mean \(\|a\|^2\) in the denominator, or \(a\cdot a\)?
