I need help, but please try not to give me the answer: it says let v1=(3,5) and v2=(-4,7) compute |v1| and |v2|

    |v1| = distance of the vector v1. Do you know the formula?

    if v = (a,b) |v| = sqrt(a^2 + b^2)

    Okay, but what about |v2| |V1|= sqrt(3^2+5^2)=5.83 |v2|=sqrt(-4^2+7^2)=8.06 Am I right?

    It's basically the pythagorean theorem. This is leaning a bit more towards physics (for me) but I think the notation is similar in a sense.

    I get the same answer but I'm not sure If the methodology is the same.
