    Vectors

    Dear forum members,


    please help me verify if the vectors \vec{a}=4i+3j and \vec{b}=\frac{-1}{3}i+\frac{-1}{4}j are parrallel. \frac{-1}{12}*\vec{a}=\vec{b} So, does this prove they are parrallel?

    Yes it does. k*\vec{a} (k being a scaler) only extends, shortens or reverses the vector. The line that the vector is on doesn't change.
