What does with respect to the positive x-axis mean?

What does with respect to the positive x-axis mean?

If you want to measure it with respect to the x axis it means that you start on the x – axis and move counter clockwise to your angle.

What is the angle with respect to the x-axis?

If the vector is pointing along the positive x-axis, then the angle is 0˚ (0 radians). If it is pointing along the negative x-axis, then the angle is 180˚ (π radians).

What does with respect to the origin mean?

Describes a graph that looks the same upside down or right side up. Formally, a graph is symmetric with respect to the origin if it is unchanged when reflected across both the x-axis and y-axis. See also.

How do you know if a graph is symmetric with respect to the x-axis?

If a function is symmetric with respect to the x-axis, then f (x) = – f (x). The following graph is symmetric with respect to the y-axis (x = 0). Note that if (x, y) is a point on the graph, then (- x, y) is also a point on the graph.

What is a positive x direction?

The positive direction of x-axis or y-axis means the positive values of the x,y coordinates.

What is the vector of x axis?

Vectors in Three Dimensions In the Cartesian coordinate system, the first two unit vectors are the unit vector of the x-axis ^i and the unit vector of the y-axis ^j . The third unit vector ^k is the direction of the z-axis ((Figure)).

What is an angle with respect to the horizontal?

Horizontal angles are usually expressed in degrees . A full circle is divided into 360 degrees , abbreviated as 360° . a 90° angle , called a right angle, is made of two perpendicular lines. The corners of a square are all right angles; a 180° angle is made by prolonging a line.

What is symmetry with respect to y-axis?

Section 4-7 : Symmetry. A graph is said to be symmetric about the y -axis if whenever (a,b) is on the graph then so is (−a,b) . Here is a sketch of a graph that is symmetric about the y -axis. A graph is said to be symmetric about the origin if whenever (a,b) is on the graph then so is (−a,−b) .

What does symmetric with respect to the y-axis mean?

Functions can be symmetrical about the y-axis, which means that if we reflect their graph about the y-axis we will get the same graph. There are other functions that we can reflect about both the x- and y-axis and get the same graph. These are two types of symmetry we call even and odd functions.

What function is symmetric with respect to the y-axis?

A function symmetrical with respect to the y-axis is called an even function. A function that is symmetrical with respect to the origin is called an odd function.

Which function is symmetric with respect to the y-axis quizlet?

The graph of an even function is symmetric with respect to the y-axis.
