Question

If a vector A make angles alpha, beta and gamma respectively, with the X. Y and Z axes, then sin square
alpha+sin square Beta+ sin square gamma
=​

Answer 1

Answer:

2

Explanation:

vector A makes angles alpha , beta , gamma with the axes

ie. cos square alpha + cos square beta + cos square gamma = 1

ie. 1 - sin square alpha + 1 - sin square beta + 1 - sin square gamma = -2

therefore:- sin square alpha + sin square beta + sin square gamma = 2 .
