What are the direction cosines of the y-axis?

To find : Direction cosines of the y- axis

Formula used : If a line makes angles α^o, β^o and γ^o with the positive directions of x-axis, y-axis and z-axis respectively. then direction cosines are given by , ,

y-axis makes 90 ^o with the x and z axes

α = 90^o, β = 0 ^o and γ = 90 ^o

Direction cosines of the line is

, ,

0, 1, 0

Direction cosines of the line is 0, 1 , 0
