3. Find the magnitude and unit vector in the direction of vectorvectorA=i-2j+k.​

Answer 1

Explanation:

We find its magnitude using the Pythagorean Theorem or the distance formula, and we find its direction using the inverse tangent function. Given a position vector →v=⟨a,b⟩,the magnitude is found by |v|=√a2+b2. The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application.
