حاصل طرح المتجهين :
A with rightwards arrow on top equals 3 i with hat on top plus 4 j with hat on top space space space space comma space space space space space B with rightwards arrow on top equals i with hat on top minus j with hat on top

Answer 1

المتجه A:
A = 3i + 4j
المتجه B:
B = i - j
حاصل الطرح:
A - B = (3i + 4j) - (i - j)
A - B = 3i + 4j - i + j
A - B = (3 - 1)i + (4 + 1)j
A - B = 2i + 5j
إذاً، حاصل الطرح للمتجهين A و B هو:
2i + 5j
