Polar Coordinate System ★ video in HINDI ★ EduPoint

In this Physics / Mathematics video lecture in HINDI we explained the polar coordinate system comparing with rectangular Cartesian coordinate system with the help of graph. Polar Coordinate system is used to represent a point in two dimensional plane. We also explained how to transform those systems into each other, i.e., how to represent a point, depicted in rectangular coordinate system, in polar coordinate system and vice versa. ★★★★★★★★★★★★★★★★ Watch the video on Spherical Coordinate System :    • Spherical Coordinate System ★ video in HIN...   Watch the video on Cylindrical Coordinate System :    • Cylindrical Coordinate System ★ video in H...   ★★★★★★★★★★★★★★★★ In Mathematics / Physics, 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 radial coordinate is often denoted by r or ρ, and the angular coordinate by ϕ, θ, or t. The angular coordinate is specified as ϕ by ISO standard. Angles in polar notation are generally expressed in either degrees or radians (2π rad being equal to 360°). Radians are more common in mathematics and mathematical physics. In many contexts, a positive angular coordinate means that the angle ϕ is measured counterclockwise from the axis. In mathematical literature, the polar axis is often drawn horizontal and pointing to the right. The polar coordinates r and ϕ can be converted to the Cartesian coordinates x and y by using the trigonometric functions sine and cosine: x=r cos ϕ y=r sin ϕ The Cartesian coordinates x and y can be converted to polar coordinates r and ϕ with r ≥ 0 and ϕ in the interval (−π, π] r=sqrt (x^2+y^2) ϕ = inverse tangent of (y,x) In upcoming videos we will talk about the cylindrical coordinate system and spherical coordinate system. ★★★★★★★★★★★★★★★★ Click to visit the homepage of our channel :    / @edupoint.physics   EduPoint, Dam Road, Chandil, Dist- Seraikela-Kharsawan, Jharkhand, India.
