Question

Чертежнику был дан для исполнения следующий алгоритм: сместиться на (1,2) сместиться на (-2,2)сместиться на (4,-4) конец каковы координаты точки,с которой чертёжник начал движение, если в конце он оказался в точке (0,0)

Answer 1

Если не ошибаюсь, то (-3;-8)
Нужно сложить все иксы вместе и все игрики(х; у), а т.к. нужно начальную точку узнать, то меняем знаки на противоположные.

Answer 2

Algorithm Execution and Initial Point

The given algorithm instructs the drafter to perform the following movements: 1. Shift by (1,2) 2. Shift by (-2,2) 3. Shift by (4,-4)

To determine the initial point from which the drafter began the movement, given that they ended up at the point (0,0), we can calculate the reverse movements to find the starting point.

Calculation of Initial Point

To calculate the initial point, we can reverse the given movements. Starting from the end point (0,0), the reverse movements would be: 1. Shift by (-4, 4) 2. Shift by (2, -2) 3. Shift by (-1, -2)

By performing these reverse movements from the end point (0,0), we can determine the initial point from which the drafter began the movement.

The initial point from which the drafter began the movement, given that they ended up at the point (0,0), is (-3, 0).
