In Mathematics, the cartesian plane is defined as a two-dimensional coordinate plane, which is formed by the intersection of the x-axis and y-axis. The x-axis and y-axis intersect perpendicular to each other at the point called the origin.
Q. How do you find Cos negative theta?
cos(-θ) = cos θ & sin(-θ) = – sin θ. These are the negative angle identities. Although the diagram shows the angle θ in the first quadrant, the same conclusion can be reached when θ lies in any quadrant, and so the negative angle identities hold for all angles θ.

Q. Is CSC negative or positive?
In quadrant II, “Smart,” only sine and its reciprocal function, cosecant, are positive. In quadrant III, “Trig,” only tangent and its reciprocal function, cotangent, are positive.
Q. What is the 4th quadrant on a graph?
Quadrant IV: The fourth quadrant is in the bottom right corner. X has positive values in this quadrant and y has negative values.
Q. What is Cartesian plane math?
A Cartesian plane (named after French mathematician Rene Descartes, who formalized its use in mathematics) is defined by two perpendicular number lines: the x-axis, which is horizontal, and the y-axis, which is vertical. Using these axes, we can describe any point in the plane using an ordered pair of numbers.
Q. What is Cartesian plane class 9?
Cartesian Plane: A cartesian plane is defined by two perpendicular number lines, A horizontal line(x−axis) and a vertical line (y−axis). These lines are called coordinate axes. Origin: The coordinate axes intersect each other at right angles, The point of intersection of these two axes is called Origin.
Q. Why is the XY plane called the Cartesian plane?
The Cartesian Plane is sometimes referred to as the x-y plane or the coordinate plane and is used to plot data pairs on a two-line graph. The Cartesian plane is named after the mathematician Rene Descartes who originally came up with the concept. Cartesian planes are formed by two perpendicular number lines intersect.
