The line segment starting from the center of the graph going to the right (called the positive x-axis in the Cartesian system) is the polar axis. The center point is the pole, or origin, of the coordinate system, and corresponds to r=0.Apr 27, 2019
What is a pole of a line?
The pole of a line L in a circle C is a point Q that is the inversion in C of the point P on L that is closest to the center of the circle. Conversely, the polar line (or polar) of a point Q in a circle C is the line L such that its closest point P to the center of the circle is the inversion of Q in C.
What is mean by pole of a circle?
If tangents to the circle at A and B meet at Q, then locus of Q is called the polar of P with respect to circle and P is called the pole and if tangents to the circle at A' and B' meet at Q', then the straight line QQ' is polar with P as its pole.
What is the pole of a parabola?
Pole and polar of a parabola Suppose any straight line drawn through P intersects the parabola at Q and R. Then the locus of the point of intersection of the tangents to the parabola at Q and R is called the polar of the given point P w.r.t. the parabola and the point P itself is called the pole of the polar.
What is the pole in trig?
Second in importance is the polar coordinate system. It consists of a fixed point 0 called the pole, or origin. Extending from this point is a ray called the polar axis. This ray usually is situated horizontally and to the right of the pole.
What is the pole formula?
Polar of a point Consider a point P inside or outside ellipse and a line passing through ellipse intersecting it at points Q and R . Then the locus of point of intersection of tangents at Q and R is called polar. Point P is called the pole. a2xx1+b2yy1=1 is the equation of polar, where (x1,y1) is the pole.
How do you find the number of poles?
The actual running speed is the synchronous speed minus the slip speed. To determine the number of poles, you can read the data plate directly or calculate it from the RPM stated on the data plate or you can count the coils and divide by 3 (poles per phase) or by 6 (pairs of poles per phase).
What is the pole conics?
The concept of poles and polars can also be generalized to arbitrary conic sections. If two tangents to a conic section at points and meet at , then is called the inversion pole of the line with respect to the conic and is said to be the polar of the point. with respect to the conic (Wells 1991).
How do you represent a line in polar coordinates?
Thus, the equation of a line through the origin is represented by the equation q = a in polar coordinates. where p is the distance of the line from the pole O and j is the angle that the segment p makes with the polar axis.

How tall is the pole formula?
The height of the pole is h plus the height of the student from his feet to his eyes. This height of the student is 4 feet which is 1.22 m thus the height of the pole is h + 1.22 m.
How do you find the height of a pole?
The most accurate method for measuring the height of a flagpole is to use a surveyor's theodolite to measure the angle of elevation and the distance from the base of the pole. With that information, you can calculate the height from the tangent of the angle of elevation.
Is Pole and Polar of circle in JEE syllabus?
Pole and Polar is not in JEE syllabus but they do make solution to some problem easy.
What is the polar equation of a circle?
Polar Equation of a Circle We know that the equation of circle centered at the origin and having radius 'p' is x2 + y2 = p2.

· Polar coordinates use a different kind of graph instead, based on circles: The center point of the graph (or "origin" in a rectangular grid) is the pole. You can label this with the letter O. Starting from the pole, draw a horizontal line to the right. This is the polar axis. Label the axis with units as you would the positive x-axis on a ...

A geographical pole or geographic pole is either of the two points on Earth where its axis of rotation intersects its surface. The North Pole lies in the Arctic Ocean while the South Pole is in Antarctica.North and South poles are also defined for other planets or satellites in the Solar System, with a North pole being on the same side of the invariable plane as Earth's North pole.

Thus, Cartesian coordinates can be converted into polar coordinates by using the below-given formula: The value of \(\tan^{-1} \left( \dfrac {y}{x} \right) \) for converting Cartesian coordinates to polar coordinates may need to be adjusted as per the quadrant in which the point lies:

In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point (analogous to the origin of a Cartesian coordinate system) is called the pole, and the ray from the pole in the reference direction is the polar axis.

An online polar coordinates calculator will display the conversion of polar to Cartesian coordinate and Cartesian to polar coordinates. This calculator provides the stepwise results for the 2-D space of 3-D coordinates. Let’s take a look at how to convert polar coordinates to rectangular coordinates and vice versa using their formulas.

We will look at polar coordinates for points in the xy-plane, using the origin (0;0) and the positive x-axis for reference. A point P in the plane, has polar coordinates (r; ), where r is the distance of the point from the origin and is the angle that the ray jOPjmakes with the positive x-axis.

· Imagine your compass pointing south instead of north. If you were alive to see it 800,000 years ago, it would have been the Magnetic South Pole.. It takes 200,000 to 300,000 years for Earth’s magnetic field to flip polarity.Flipping polarity means the lines of attraction that enter the Earth would flip north to south pole, or vice versa.

similar to that of the rectangular coordinate system. In a polar coordinate grid, as shown below, there will be a series of circles extending out from the pole (or origin in a rectangular coordinate grid) and five different lines passing through the pole to represent the angles at which the exact values are known for the trigonometric functions.
