Find the magnitude and direction angle of the following vector. Write your angle in degrees rounded to four decimal places.u=−12i−7j
Question
Solution 1
The magnitude of a vector u = -12i - 7j is calculated using the formula:
||u|| = sqrt((-12)^2 + (-7)^2)
The direction angle (θ) of the vector is calculated using the formula:
θ = atan2(y, x), where x and y are the i and j components of the vector respectively.
Let's calculate:
