Consider the following relations among the angles alpha,beta and gamma What is the angle between the lines whose direction cosines are propor What is the locus of points of intersection of a sphere and a plane?

In analytical geometry, the directional cosines also known as direction cosine of a vector is defined as the cosines of the angles between the three coordinate axes and the vector. In this section, we will first learn about the position vector of a point and direction cosines and then finding the angle between two lines. Position vector simply denotes the position or location of a point in the three-dimensional Cartesian system with respect to a reference origin. Taking direction cosines makes it easy to represent the direction of a vector in terms of angles with respect to the reference. The coordinates of the point P may also be expressed as the product of the magnitude of the given vector and the cosines of direction on the three axes, i. Where l, m, n represent the direction cosines of the given vector on the axes x, y, z respectively.

The angle between the lines whose direction cosines

Direction cosine is the cosine of the angle made by the line in the three-dimensional space, with the x-axis, y-axis, z-axis respectively. Direction cosines can be calculated for a vector or a straight line in a three-dimensional space. It is the cosines of the angle made by the line with the three axes. Let us learn more about the direction cosine, the relationship between the direction cosines, and the direction cosine of a line connecting two points in a three-dimensional space.
