Question

A(2,5) b(4,7) C(5,5) k(3,5) s(7,8) n(9,6)
найдите координаты векторов A B , A C , AK , S N​

Answer 1

Ответ:

A⃗B⃗ = (bx-ax, by-ay) = (4-2, 7-5) = (2, 2)

A⃗C⃗ = (cx-ax, cy-ay) = (5-2, 5-5) = (3, 0)

A⃗K⃗ = (kx-ax, ky-ay) = (3-2, 5-5) = (1, 0)

S⃗N⃗ = (nx-sx, ny-sy) = (9-7, 6-8) = (2, -2)
