In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate. The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx. Hence, the change in y-coordinate with respect to the change in x-coordinate is given by, m = change in y/change in x = Δy/Δx.

9 Ιαν 2024 · CBSE Class 12 Maths Notes Chapter 11 Three Dimensional Geometry. Direction Cosines of a Line: If the directed line OP makes angles α, β, and γ with positive X-axis, Y-axis and Z-axis respectively, then cos α, cos β, and cos γ, are called direction cosines of a line. They are denoted by l, m, and n. Therefore, l = cos α, m = cos β and n ...
