The above figure indicates the smaller portion of the curve dS with the coordinates as follows, P = (r, θ), Q = (r + dr, θ + dθ) From the above figure, OP = r. OQ = r + dr. WebThe diameter symbol in engineering, ⌀, is often erroneously referred to as "phi", and the diameter symbol is sometimes erroneously typeset as Φ. This symbol is used to indicate the diameter of a circular section; for example, "⌀14" means the diameter of the circle is 14 units . A clock signal in electronics is often called Phi or uses the symbol.

WebIn differential geometry, the radius of curvature (Rc), R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is the radius of a circle that best fits a normal section or combinations thereof. [1] [2] [3] Definition [ edit]
