Equation of a Line in Space: This section explains how to find the equation of a line in space using various methods, such as the point-slope form and the symmetric form.
Important Terms Every Student Must Know about Three Dimensional Geometry:
Direction Cosines and Direction Ratios:
Direction cosines and direction ratios are fundamental concepts in Three Dimensional Geometry. Direction cosines refer to the cosines of the angles made by a line with the positive directions of the coordinate axes. On the other hand, direction ratios refer to the ratios of the lengths of the line segments intercepted by the line on the coordinate axes. In this section, students will learn how to find the direction cosines and direction ratios of a line in space.
Distance between two points:
The distance formula for two points in the coordinate plane can be easily extended to three dimensions. In this section, students will learn how to find the distance between two points in three-dimensional space using the distance formula. This formula involves finding the square root of the sum of the squares of the differences in the x, y, and z-coordinates of the two points.
Section Formula:
The section formula is used to find the coordinates of the point that divides a line segment joining two given points in a given ratio. In this section, students will learn how to find the coordinates of the point using the section formula. This formula can be applied to any line segment in three-dimensional space.
Equation of a Line in Space:
In this section, students will learn how to find the equation of a line in space using various methods, such as the point-slope form and the symmetric form. The point-slope form involves finding the slope of the line and the coordinates of a point on the line. The symmetric form involves finding the direction ratios of the line and the coordinates of a point on the line.
