I’ve got a question that asks me for a value of a vector at a particular time. It is just basic addition but I’m not sure about the form of the answer. Should I leave it as w=(x, y, z) or calculate the absolute value of the vector?
Edit: z=[0, 0, sin(c)] d=[c, cos(c),0] f=z+d It’s simple vector addition. I’m supposed to find the value of f at c=0. Should I leave it as [0, 1, 0] or calculate the absolute value which is 1?
The value of $f$ is different from the norm of $f$.
Just leave it as $[0,0, \sin(0)] + [0,\cos(0), 0]= [0,1,0]$ as you computed.
