Question

The angle which the vector Abar=3icap+6jcap+2kcap makes with the coordinate axes are

Answer 1

Answer:

krna kya hai yarrrr......

Answer 2

Answer:

A = 3 i + 6 j + 2 k

Magnitude of A is (3^2 + 6^2 + 2^2)^1/2 = 7

cos theta-x = 3/7      theta-x = 64.6 deg

cos theta-y = 6/7      theta-y = 31 deg

cos theta-z = 2/7      theta-z = 73.4 deg

These are known at the direction cosines of A
