Question

Please help me with this problem in the picture, its about trigonometry.

Answer 1

• Yes, vector u and vector v are equivalent vectors.

Explanation:

The value of a vector is the difference between its terminal point and its initial point:

u = P2 -P1 = (6-8, 5-3) = (-2, 2)

v = P4 -P3 = (9-11, 10-8) = (-2, 2)

Vectors u and v are both (-2, 2), so are equivalent vectors.
