Cartesian equation of a line

Vectors can be defined as a quantity possessing both direction and magnitude. Position vectors simply denote the position or location of a point in the three-dimensional Cartesian system with respect to a reference origin.

A line is a one-dimensional figure that only has length and no width. In this article, we will learn about the equation of a line on a cartesian plane. A line is a one-dimensional figure that only has length; it has no width. The cartesian plane allows the representation of the equation of a figure in three-dimensional analysis. The x-axis, y-axis, and z-axis represent the equation of a line on a cartesian plane.

Cartesian equation of a line

The cartesian form helps to represent geometric entities in the cartesian plane. A point, a line, or a plane can be easily represented in a three-dimensional plane, across the x-axis, y-axis, z-axis, in cartesian form. The cartesian form is helpful to represent the geometric entities as algebraic expressions in three-dimensional geometry. Let us learn more about the conversion of cartesian form to vector form, the difference between cartesian form and vector form, with the help of examples, FAQs. The cartesian form helps in representing a point, a line, or a plane in a two-dimensional or a three-dimensional plane. The cartesian form is represented with respect to the three-dimensional cartesian system and is with reference to the x-axis, y-axis, and z-axis respectively. The representation of a point in a three-dimensional cartesian plane is x, y, z , and each of x,y, z represent the coordinates of the points with respect to the x-axis, y-axis, and z-axis respectively. The cartesian form can be easily transformed into vector form, and the same vector form can be transformed back to cartesian form. This can be done using two simple techniques. Secondly, the formula of the product of unit vectors is helpful in converting the cartesian form to vector form.

If you have ever played video games, you may not know it, but under the hood is a heap of 3D geometry being used to give you the best experience. Just one example of this is ray tracing: a method of simulating light within video games to make it seem natural. Ray tracing is done by modelling lots of rays of light coming in a straight line from the light source, and seeing which targets they hit. This allows the positions of shadows and reflections to be calculated accurately, to make an immersive, realistic-looking world. This is just one example of how 3D geometry, and in particular 3D lines, are used in everyday life. Explore our app and discover over 50 million learning materials for free.
