A binary function is a function f if there exists sets X, Y, and Z, such that f:X x Y -> Z where X x Y is the cartesian product of X and Y.
It is the Cartesian equation of an ellipse.
Quadrant.
In cartesian coordinates (x, y) = (3, -4)
If: y = 5x and y = 3 -x Then: 5x = 3 -x => 5x +x = 3 => 6x = 3 => x = 1/2 By substitution point of contact is at: (1/2, 5/2)
coords are coordinates. the X/Y axis of where you are located on a map
If spherical coords are r and theta, then x = r*cos(theta) and y = r*sin(theta) Conversely, r = sqrt(x2 + y2) and theta = arctan(y/x) provided x is not zero. and theta = 90 deg when x = 0
the equation that convert from cartesian to polar coordinates and vice versa r = sqrt (x*x+y*y); phi = atan2 (y, x); x = r*cos (phi); y = r*sin (phi);
Cartesian coordinates.
They are the x and y axes
( x y z )
The 'abscissa' is the x coordinate on the Cartesian plane and the 'ordinate' is the y coordinate on the Cartesian plane
Cartesian coordinates
Cartesian coordinates (x,y) were invented by Rene Descartes in the 17th Century.
A binary function is a function f if there exists sets X, Y, and Z, such that f:X x Y -> Z where X x Y is the cartesian product of X and Y.
The x-coordinate is the horizontal part of what is known as the cartesian plane, which is the 2D representation of dimensioning. This is a cartesian plane: /\ <------------- that's an arrow, which means it extends indefinitely. | | | <-----------|----------> X ( this is the x coordinate, the horizontal part of the cartesian plane) | | | V Y (This is the y coordinate, the vertical part) jhj
(x,y,z) hi APEX ppl! TB
