Written on in English with a size of 2.29 KB

Defining the Environment

The word environment is derived from the French word meaning 'to surround'. Thus, it refers to the sum total of conditions that surround humans at a given point in space and time. It is a composite term for the conditions in which organisms live. In other words, the environment is the totality of all physical, social, and biological factors that comprise the natural and man-made surroundings.

Types of Environment

Considering its basic structure, the environment may be divided into two broad types:

Parametric Equations: Lines, Circles, and Motion in 3D Space

Classified in Physics

Written on in English with a size of 5.23 KB

Example 2: Find parametric equations for a particle that starts at (0, 3, 0) and moves around a circle as shown in Figure 17.1. The circle has a radius of 3 in the yz-plane, centered at the origin.

Solution: Since the motion is in the yz-plane, we have x = 0 at all times t. Looking at the yz-plane from the positive x-direction, we see motion around a circle of radius 3 in the clockwise direction. Thus, the parametric equations are:

  • x = 0
  • y = 3cos(t)
  • z = -3sin(t)

Example 3: Describe in words the motion given parametrically by x = cos(t), y = sin(t), z = t.

Solution: The particle's x- and y-coordinates give circular motion in the xy-plane, while the z-coordinate increases steadily. Thus, the particle traces out a rising spiral, like a coiled spring.... Continue reading "Parametric Equations: Lines, Circles, and Motion in 3D Space" »
