Find the equation of line parallel to x-axis and passing through the origin |
|
Answer» TION.Equation of the line parallel to x-axis passing through the origin.Direction cosines the line making,α with x-axis, β with y-axis, γ with z-axis are x, y, z.x = Cosα, y = Cosβ, z = Cosγ.⇒ x = Cos(0)°.⇒ y = Cos(90°).⇒ z = Cos(90°).⇒ x = 1.⇒ y = 0.⇒ z = 0.Direction Cosines of x-axis = (1,0,0). MORE INFORMATION.Equation of line.(1) = VECTOR form.Equation of line passing through and parallel to vector .(2) = CARTESIAN form.Equation of a straight line passing through a fixed point (x₁, y₁, z₁) and having direction RATIOS a, b, c.x - x₁/a = y - y₁/b = z - z₁/c.Equation of a line passing through two given POINTS.(1) = Vector form.Equation of line passing through two points and (2) = Cartesian form.Equation of a line passing through two given points (x₁, y₁, z₁) and (x₂, y₂, z₂) is given by.x - x₁/x₂ - x₁ = y - y₁/y₂ - y₁ = z - z₁/z₂ - z₁. |
