Mathematics in Plain English – What Is a Vector
A vector is nothing more than a directed line segment. Technically speaking, a vector is defined as an object that has both a size, or magnitude, and a direction. Vectors have many applications in mathematics and are found abundantly in fields like physics and engineering. Examples of vectors are velocity, acceleration, and force.
Vectors are defined by their size and direction. For example, velocity is a vector because we can describe this quantity by both its size, that is speed, and its direction. Thus a car moving at 60 miles per hour in a direction due north exemplifies a velocity vector. Acceleration also typifies a vector because this quantity has both a size and direction. A truck accelerating at 10 feet per second per second moving due south exemplifies an acceleration vector. Force is another object which is modeled by a vector quantity. A force of 15 Newtons (on earth this is a weight of about 3lbs) exerted downward is an example of a vector.
In the Cartesian Plane—the grid on which we graph points, lines, and curves—a vector can be given as a point. For example, in two dimensions the point (1, 0) represents the vector starting at the origin (we say having its tail at the origin) pointing to the right and terminating (we say having its head) one unit from the origin. The point (0, 1) represents the vector having its tail at the origin, pointing straight up and having its head one unit from the origin. The point (1, 1) represents the vector having its head once again at the origin and its tail at the point (1, 1); this vector lies on the line which bisects the first quadrant.
How to Get Over Your Anxiety While Studying For a Test
As a professional private tutor I’ve been helping students of all ages get ready for tests for years now.
Anxiety is a factor that sometimes cripples a student’s performance for no good reason at all. Exam anxiety is largely a figment of one’s imagination yet real in its effects.
Here is my Number One recommendation to all students who’d like to get test anxiety under control:
Prepare, prepare, and then prepare some more again.
