Question

an angle between A vector =3i cap - 4j cap -2k cap and B vector =8i cap+3j cap+6k cap is..​

Answer 1

Answer:theta=90

Explanation:

AB cos theta=3*8-4*3-2*6

ABcos theta=24-24

ABcostheta=0

Costheta=0

we know that ,cos 90 degree=0

Therefore,theta =90

Answer 2

Answer:

Explanation:

theta=90

AB cos theta=3*8-4*3-2*6

AB cos theta=24-24

AB cos theta=0

Cos theta=0

we know that ,cos 90 degree=0

Therefore,theta =90 degrees
