Hace 4 días · In this explainer, we will learn how to find the parametric equations of straight lines in space. Let us remind ourselves first about the different forms of equations of a straight line in the 𝑥 𝑦 -plane (i.e., in two dimensions, 2D). The form 𝑦 = 𝑚 𝑥 + 𝑏 gives us the slope 𝑚 and the 𝑦 -intercept 𝑏.
Hace 4 días · Write the vector, parametric, and symmetric equations of a line through a given point in a given direction, and a line through two given points. Find the distance from a point to a given line. Write the vector and scalar equations of a plane through a given point with a given normal.
Hace 1 día · General relativity, also known as the general theory of relativity, and as Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation ...
Hace 4 días · Consider the equation of a straight line through the origin, 𝑦 = 𝑟 ℎ 𝑥, as shown in the plot. We can rotate this line between 𝑥 = 0 and 𝑥 = ℎ by a complete revolution about the 𝑥 -axis to form a cone of radius 𝑟 and vertical height ℎ, as shown in the diagram.
Hace 4 días · In this lesson, we will learn how to calculate the perpendicular distance between a point and a straight line or between two parallel lines in space using a formula.
