What is the pole of polar coordinates?
That is the origin O, from which all angles and distances to the point are measured, instead of measuring distance from the axes. In bipolar coordinates, there are two poles, from which angles are both measured to determine the distance.
What do you need to use the point slope formula?
The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.
What gives the coordinates and location of a point?
An ordered pair gives coordinates and location
What are 2 polar coordinates for the point -3 -3?
The point whose Cartesian coordinates are (-3, -3) has the polar coordinates R = 3 sqrt(2), Θ = -0.75pi.
How homogenous co-ordinate system differ from cartesian system?
We assume that the ambient space is equipped with the standard Cartesian coordinate system and specify points by their Cartesian coordinates.The Cartesian coordinates of a point in the plane are a pair (x,y).The homogeneous coordinates of a point in the plane are a triple (x,y,w) with w!=0. The Cartesian coordinates of a point with homogeneous coordinates (x,y,w) are (x/w,y/w).Remark: We notice that the homogeneous coordinates of a point are not unique. Two triples that are multiples of each other specify the same point.The Cartesian coordinates of a point are of type double in the floating point kernel and of type rational in the rational kernel. The homogeneous coordinates of a point in the rational kernel are of type integer. Points in the floating point kernel are stored by their Cartesian coordinates.For points in the rational kernel it is more efficient to store them by their homogeneous coordinates, i.e., to use the same denominator for x- and y-coordinate.For compatibility also points in the floating point kernel have homogeneous coordinates (x,y,1.0). These homogeneous coordinates are of type double.
What are absolute and relative coordinates system?
In the absolute coordinate system, positions are measured from a fixed reference point, such as the origin (0,0). In contrast, relative coordinates are measured in relation to a starting point, like a previous position or object. Absolute coordinates provide definitive positions, while relative coordinates are used to describe movements or relationships between objects.
In math how do rotations affect coordinates?
A rotation turns a shape through an angle at a fixed point thus changing its coordinates
What is the definition of an origin as a math term?
It is a fixed reference point in space from which distances are measured.
What is rectangular cartesian coordinates?
A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system.
What is the pole of polar coordinates?
That is the origin O, from which all angles and distances to the point are measured, instead of measuring distance from the axes. In bipolar coordinates, there are two poles, from which angles are both measured to determine the distance.
What is the number of waves per second passing a fixed point measured in?
The number of waves passing a fixed point per second is known as the frequency of the wave, and it is measured in hertz (Hz).
What is a topocentric?
relating to, measured from, or as if observed from a particular point on the earth's surface : having or relating to such a point as origin (e.g. topocentric coordinates)
What is the way you will see a reference point is considered?
A reference point is typically considered as a fixed location or object that other positions or movements are measured relative to. It serves as a basis for comparison or orientation in a system of coordinates or in describing the motion of objects. The reference point provides a frame of reference for analyzing and interpreting data.
Why do we always start at the origin point?
It is because many things are measured with reference to a fixed point: it space or time. This point is called a reference point or origin.
The of a wave is the number of wavelengths that pass a fixed point in a second?
The frequency of a wave is the number of complete wavelengths that pass a fixed point in one second. It is measured in hertz (Hz).
What does reference point mean when having to do with speed?
A reference point in the context of speed is a fixed location from which the speed of an object is observed or measured. It provides a frame of reference for determining the speed of an object relative to that fixed point.
What is a fixed point on the map?
A fixed point on a map is a specific location with known coordinates that doesn't change. It serves as a reference point for navigation, cartography, and surveying purposes. Fixed points can include landmarks, monuments, or specific geographic features that are used to help orientate and locate other places on the map.
