You can put this solution on YOUR website! Given the vector → u = ⟨ 1 , 4 ⟩ u→=〈1,4〉, find the magnitude and angle in which the vector points (measured counterclockwise from the positive x-axis, 0 ≤ θ < 2 π 0≤θ<2π)
---------------------
The vector is from (0,0) to (1,4)
Magnitude is the length.
==============
tan(t) = y/x
