That is, for \(N\) a positive infinite integer, let, \[d x=\frac{b-a}{N},\] and \[d y=f(x+d x)-f(x).\] If the shadow of \[\sum_{i=1}^{N} \sqrt{1+\left(\frac{d y}{d x}\right)^{2}} d x.\] is the same for any choice of \(N,\) then we call \((2.5 .27)\) the arc length of \(C .\) Now if \(f\) is differentiable on an open interval containing \([a, b],\) and \(f^{\prime}\) is continuous on \([a, b],\) then \((2.5 .27)\) becomes the definite integral of \(\sqrt{1+\left(f^{\prime}(x)\right)^{2}} .\) That is, the arc length of \(C\) is given by \[L=\int_{a}^{b} \sqrt{1+\left(f^{\prime}(x)\right)^{2}} d x.\], Let \(C\) be the graph of \(f(x)=x^{\frac{3}{2}}\) over the interval \([0,1]\) (see Figure \(2.5 .11)\) and let \(L\) be the length of \(C .\) since \(f^{\prime}(x)=\frac{3}{2} \sqrt{x},\) we have, \[L=\int_{0}^{1} \sqrt{1+\frac{9}{4} x} d x.\] Now \[\int \sqrt{x} d x=\frac{2}{3} x^{\frac{3}{2}}+c,\] so we might expect an integral of \(\sqrt{1+\frac{9}{4}}\) to be \[\frac{2}{3}\left(1+\frac{9}{4} x\right)^{\frac{3}{2}}+c.\] However, \[\frac{d}{d x} \frac{2}{3}\left(1+\frac{9}{4} x\right)^{\frac{3}{2}}=\frac{9}{4} \sqrt{1+\frac{9}{4} x},\] and so, dividing our original guess by \(\frac{9}{4},\) we have \[\int \sqrt{1+\frac{9}{4}} x d x=\frac{8}{27}\left(1+\frac{9}{4} x\right)^{\frac{3}{2}}+c,\] which may be verified by differentiation. There are basically two types of integrals, Definite and Indefinite. Area Between Curves – In this section we’ll take a look at one of the main applications of definite integrals in this chapter. lol it did not even take me 5 minutes at all! \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\), [ "article:topic", "license:ccbyncsa", "showtoc:no", "authorname:dsloughter", "Area Between Curves" ], \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}} } \) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash {#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\), 2.4: The Fundamental Theorem of Integrals, 2.6: Some Techniques for Evaluating Integrals. In this section we will look at several examples of applications for definite integrals. Here are a set of practice problems for the Applications of Integrals chapter of the Calculus I notes. /Filter /FlateDecode Chapter 6 : Applications of Integrals. Leibnitz (1646-1716) 288 MATHEMATICS There is a connection, known as the Fundamental Theorem of Calculus, between indefinite integral and definite integral which makes the definite integral as a practical Hence the integral, which is the area of \(R^{+}\) minus the area of \(R^{-},\) is \(0 .\). Let \(P\) be a pyramid with a square base having corners at \((1,1,0),(1,-1,0),(-1,-1,0),\) and \((-1,1,0)\) in the \(x y\) -plane and top vertex at \((0,0,1)\) on the \(z\) -axis. CHAPTER 6 APPLICATIONS OF THE DEFINITE INTEGRAL We may employ the following intuitive method for remembering this limit of sums formula (see Figure 6.5): 1. Given a line, which we will call the \(z\)-axis, let \(V(a, b)\) be the volume of \(B\) which lies between planes which are perpendicular to the \(z\)-axis and pass through \(z=a\) and \(z=b .\) Clearly, for any \(a.
