Explanation In simple words, arc length is defined as the length of a curve or line. The length of an arc can be found by one of the formulas below for any differentiable curve (function) defined by rectangular, polar, or parametric equations. Mathematically, the integral of a function over an interval [ a , b ] is known as the arc length of the curve or function. It defines the area under the function over that interval. This process of determining the arc length of a curve (function) is called rectifying the curve. For any real-valued function y = f ( x ) and d y d x = f ' ( x ) are continuous over the interval [ a , b ] the arc length s of the curve is defined as s = ∫ a b d s . Depending on the form of the function, ds has different forms: i) for rectangular coordinates, d s = 1 + ( d y d x ) 2 d x ii) for polar coordinates, d s = r 2 + ( d r d θ ) 2 d θ iii) for parametric equations, d s = ( d x d t ) 2 + ( d y d t ) 2 d t Given: To define arc length.

Angles in Circles

Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made p…

Arcs in Circles

A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
