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.

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.

प्रवणता के लिए tan ही क्यों लिया जाता है थीटा की वैल्यू कोश या साइन से भी तो निकाल सकते हैं???
tan की आवश्यकता ही क्यों हुई
🙏🙏🙏🙏🙏

[@unknownsci6278]

For defining this tell me why we introduced speed in physics it is distance/time . We can use sin and cos only but for some problems and simplicity we need tan theta. And one more thing , tan theta was introduced earlier than sin and cos theta.
