Question

A vector u has initial point (2. -3) and terminal point (3.-4).

Write u in the form u= ai+bj
u= _____.

Answer 1

To write vector u in the form u = ai + bj, we need to find the values of a and b. The initial point of vector u is (2, -3) and the terminal point is (3, -4).

Step-by-step explanation:

To write vector u in the form u = ai + bj, we need to find the values of a and b.

The initial point of vector u is (2, -3) and the terminal point is (3, -4).

To find a, we subtract the x-coordinates of the terminal and initial point: a = 3 - 2 = 1.

To find b, we subtract the y-coordinates of the terminal and initial point: b = -4 - (-3) = -1.

So, vector u can be written as u = 1i - 1j.
