WebIn addition to finding a vector’s components, it is also useful in solving problems to find a vector in the same direction as the given vector, but of magnitude 1. We call a vector with a magnitude of 1 a unit vector. We can then preserve the direction of the original vector while simplifying calculations. WebFind the magnitude and direction of the vector 2 u + 3 v Solution to Question 7: Let us first use the formula given above to find the components of u and v. u = < 2 cos(90°) , 2 …
