Math Problem Statement

Let the vector vv have an initial point at left parenthesis, minus, 4, comma, 0, right parenthesis(−4,0) and a terminal point at left parenthesis, 0, comma, minus, 6, right parenthesis(0,−6). Determine the components of vector v, .v.

Solution

To find the components of the vector v, we subtract the coordinates of the initial point from the coordinates of the terminal point.

The formula to find the components of a vector is:

v=(x2x1,y2y1)\mathbf{v} = (x_2 - x_1, y_2 - y_1)

Where:

  • (x1,y1)(x_1, y_1) is the initial point,
  • (x2,y2)(x_2, y_2) is the terminal point.

Given:

  • Initial point: (4,0)(-4, 0),
  • Terminal point: (0,6)(0, -6).

Now, calculate the components:

v=(0(4),60)\mathbf{v} = (0 - (-4), -6 - 0)

Simplifying:

v=(0+4,6)=(4,6)\mathbf{v} = (0 + 4, -6) = (4, -6)

Thus, the components of vector v are v=(4,6)\mathbf{v} = (4, -6).

  1. How do you find the magnitude of a vector from its components?
  2. What is the direction of a vector, and how can it be calculated?
  3. How do you add or subtract vectors with components?
  4. What is a unit vector, and how do you find one from a given vector?
  5. How do you perform scalar multiplication on a vector?

Tip: When calculating vector components, always subtract the initial point from the terminal point to get the correct direction of the vector.
