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.
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 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 latitude and longitude based on?
Latitude is based on the equator. Longitude i sbased on Greenwich, England. The English came up with the idea, so they got to choose to reference point. ===================================== This system of locating points on the Earth's surface that we're discussing is a direct application of "spherical coordinates", familiar to anyone who has gone past high-school- junior-year math. In the mathematics of spherical coordinates, the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuth angle of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the zenith, measured from a fixed reference direction on that plane. We take that system of coordinates, place its origin at the Earth's center, set the fixed zenith direction to be the direction from the origin toward the Earth's north pole, use the Earth's radius for the radial distance of all points so that we never have to specify it, and locate any point using the two angles of its spherical coordinates.
What is the number of waves per second passing a fixed point measured in?
frequency- Hertz (Hz)
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.
What does the math term point of origin mean?
It is the point in a mathematical space from which all distances are measured. In two dimensions its coordinates are (0,0). In 3-D they are (0,0,0) and so on.
What physical quantities are measured along the axes of a position time graph?
Time and the distance from a fixed point (the origin) - either in a fixed direction or radially.
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.
A single point on a distance time graph tells the?
The vertical axis gives the distance of an object from a fixed point - the point of reference - after a time, as measured on the horizontal axis.
