The length of a curve can be calculated through definite integrals. The length of a parametric curve in the form {eq}x = f(t), y = g(t) {/eq}, on the interval {eq}a \leq t \leq b {/eq}, is computed by the formula {eq}\displaystyle L = \int_...
How to Find Equation of a Circle How to Find the Center and the Radius of Circles Formulas of Arc Length and Sector Area To find the area of a sector of a circle, use this formula: The area of a sector \(=πr^2 (\frac{θ}{360})\), \(r\) is the radius of the circle, an...
But we have seen that to add a lot of little bits together is precisely what is called integration, so that it is likely that, since we know how to integrate, we can find also the length of an arc on any curve, provided that the equation of the curve is such that it lends itself...
