Question

Найдите координаты вектора c=a-b, если a{3;-5},b{-2;4}

Answer 1

C = a-b

a {3:-5}

b {-2:4}

c {5;1}

Ответ: c {5;1}

Answer 2

To find the vector c = a - b, you simply subtract the corresponding components of vector b from vector a. The formula for the subtraction of two vectors is as follows:

c = (a_x - b_x, a_y - b_y)

where a_x and a_y are the x and y components of vector a, and b_x and b_y are the x and y components of vector b.

Given that a = (3, -5) and b = (-2, 4), we can calculate c as follows:

c_x = 3 - (-2) = 3 + 2 = 5 c_y = -5 - 4 = -9

So, the coordinates of vector c are (5, -9).
