Q. 20

# A line makes angl

Given : A line makes angles 90o, 135o and 45o with the positive directions of x-axis, y-axis and z-axis respectively.

To find : Direction cosines of the line

Formula used : If a line makes angles αo, βo and γo with the positive directions of x-axis, y-axis and z-axis respectively. then direction cosines are given by , , α = 90o, β = 135o and γ = 45o

Direction cosines of the line is , ,  , , 0, , Direction cosines of the line is 0, , Rate this question :
