If you're given a vector such as r(t) = (cost)i + (sint)j +3tk, how would you find the direction of motion?How do you find the direction of motion for a vector?evaluate r(t) as a function of t, we know that cos(t)i + sin(t)j is the equation of a circle in the plane of i-j, but as it travels around it ascends the z axis quickly at a rate of 3k
Its follows a spiral path around the z axis.How do you find the direction of motion for a vector?Hi
r' (t) = -(sin t) i + (cos t) j + 3 k
