    i think it is of two vectors.. im not sure

    if a,b are two vectors and angle between them is x then the magnitude's square is a^2+b^2+2ab cos x

    or if you're just given one vector let's say {a,b,c} then to find the magnitude of the vector then magnitude = \[\sqrt{(a^2 + b^2 +c^2)}\]

    this is possible only when the vectors are mutually perpendicular

    remember we were finding maginture of like -3 and it was 3 then the magintude of a is |a| |a|=sqrt(a^2) what about we went from (x1,y1) and (x2,y2) it was sqrt{(x1-x2)^2+(y1-y2)^2)

    for any inclined angle between them u have to add a cos x term. when the angle is 90 then the cos term vanishes nd u get a result like sqrt(a^2+b^2)

    myininaya....u gave the distance between two vectors not the magnitude of the resultant...
