| June 14, 2021 | education
Let us expand the vectors b {-1; 3} along the coordinate vectors i and j. To expand vectors in terms of coordinate vectors i and j, we need to know the formula, i.e. e.
b = x * i + y * j.
You can see the coordinates of the vector x = – 1 and y = 3, place x and y, put the value and get:
b = – i + 3 * j.
Answer: b = – i + 3 * j.
