What does this mean, you need an "affirm" of curvature?mahdi200hell said:hi

Curvature in polar coordinates is a measure of how much a curve deviates from being a straight line. It is calculated by finding the rate of change of the tangent angle along the curve.
In polar coordinates, the curvature is determined by the distance from the origin and the angle between the tangent line and the radial line. This is different from Cartesian coordinates, where curvature is determined by the second derivative of the curve.
The curvature in polar coordinates can be calculated using the formula:
κ = (r^2 + 2r'^2 - rr'') / (r^2 + r'^2)^(3/2)
where r is the distance from the origin and r' and r'' are the first and second derivatives of r with respect to the tangent angle.
Curvature in polar coordinates is important in understanding the shape and behavior of curves in polar coordinates. It can help determine the maximum and minimum points of a curve, as well as the direction in which the curve is turning.
The curvature of a curve in polar coordinates can change as the curve evolves. If the distance from the origin is constant, the curvature will only change with the change in the tangent angle. However, if the distance from the origin is changing, the curvature will also be affected by the rate of change of the distance from the origin.
