1.

The angle between vecF =(1,-3, 1)and vecd =(2,-3,-11) will b e ...... rad.

Answer»

0
`(pi)/(4)`
`(pi)/(2)`
`pi`

SOLUTION :`cos theta = (VEC(F).vec(D ))/(Fd ) = ((1,-3,-1).(2,-3,-11))/(sqrt(11)sqrt(134))`
`cos theta= (2+ 9 - 11)/(sqrt(11) squr(134))`
`=(0)/(sqrt(1474))`
`=0`
`theta= (pi)/(2)`
