What is the arc length of #f(x)=xsqrt(x^2-1) # on #x in [3,4] #? Here is a sketch of this situation . Substitute \( u=1+9x.\) Then, \( du=9dx.\) When \( x=0\), then \( u=1\), and when \( x=1\), then \( u=10\). Then, \(f(x)=1/(2\sqrt{x})\) and \((f(x))^2=1/(4x).\) Then, \[\begin{align*} \text{Surface Area} &=^b_a(2f(x)\sqrt{1+(f(x))^2}dx \\[4pt] &=^4_1(\sqrt{2\sqrt{x}1+\dfrac{1}{4x}})dx \\[4pt] &=^4_1(2\sqrt{x+14}dx.

How do you find the arc length of the curve #f(x)=x^3/6+1/(2x)# over the interval [1,3]? What is the arc length of teh curve given by #f(x)=3x^6 + 4x# in the interval #x in [-2,184]#? \[ \text{Arc Length} 3.8202 \nonumber \]. Cloudflare monitors for these errors and automatically investigates the cause. What is the arc length of #f(x)=((4x^5)/5) + (1/(48x^3)) - 1 # on #x in [1,2]#? 1. For objects such as cubes or bricks, the surface area of the object is the sum of the areas of all of its faces. Use a computer or calculator to approximate the value of the integral. How do you find the arc length of the curve #y= ln(sin(x)+2)# over the interval [1,5]? When \(x=1, u=5/4\), and when \(x=4, u=17/4.\) This gives us, \[\begin{align*} ^1_0(2\sqrt{x+\dfrac{1}{4}})dx &= ^{17/4}_{5/4}2\sqrt{u}du \\[4pt] &= 2\left[\dfrac{2}{3}u^{3/2}\right]^{17/4}_{5/4} \\[4pt] &=\dfrac{}{6}[17\sqrt{17}5\sqrt{5}]30.846 \end{align*}\]. What is the arc length of the curve given by #y = ln(x)/2 - x^2/4 # in the interval #x in [2,4]#? Our team of teachers is here to help you with whatever you need. How do you find the arc length of the curve #y=(x^2/4)-1/2ln(x)# from [1, e]? $\begingroup$ @theonlygusti - That "derivative of volume = area" (or for 2D, "derivative of area = perimeter") trick only works for highly regular shapes. Let us evaluate the above definite integral. Or, if a curve on a map represents a road, we might want to know how far we have to drive to reach our destination. lines connecting successive points on the curve, using the Pythagorean When \(x=1, u=5/4\), and when \(x=4, u=17/4.\) This gives us, \[\begin{align*} ^1_0(2\sqrt{x+\dfrac{1}{4}})dx &= ^{17/4}_{5/4}2\sqrt{u}du \\[4pt] &= 2\left[\dfrac{2}{3}u^{3/2}\right]^{17/4}_{5/4} \\[4pt] &=\dfrac{}{6}[17\sqrt{17}5\sqrt{5}]30.846 \end{align*}\]. This is important to know! where \(r\) is the radius of the base of the cone and \(s\) is the slant height (Figure \(\PageIndex{7}\)). Round the answer to three decimal places. By the Pythagorean theorem, the length of the line segment is, \[ x\sqrt{1+((y_i)/(x))^2}. Determine the length of a curve, x = g(y), between two points. Let \(r_1\) and \(r_2\) be the radii of the wide end and the narrow end of the frustum, respectively, and let \(l\) be the slant height of the frustum as shown in the following figure. Example \(\PageIndex{4}\): Calculating the Surface Area of a Surface of Revolution 1. Now, revolve these line segments around the \(x\)-axis to generate an approximation of the surface of revolution as shown in the following figure. In this section, we use definite integrals to find the arc length of a curve. First, find the derivative x=17t^3+15t^2-13t+10, $$ x \left(t\right)=(17 t^{3} + 15 t^{2} 13 t + 10)=51 t^{2} + 30 t 13 $$, Then find the derivative of y=19t^3+2t^2-9t+11, $$ y \left(t\right)=(19 t^{3} + 2 t^{2} 9 t + 11)=57 t^{2} + 4 t 9 $$, At last, find the derivative of z=6t^3+7t^2-7t+10, $$ z \left(t\right)=(6 t^{3} + 7 t^{2} 7 t + 10)=18 t^{2} + 14 t 7 $$, $$ L = \int_{5}^{2} \sqrt{\left(51 t^{2} + 30 t 13\right)^2+\left(57 t^{2} + 4 t 9\right)^2+\left(18 t^{2} + 14 t 7\right)^2}dt $$. Note: Set z (t) = 0 if the curve is only 2 dimensional. \nonumber \]. Added Apr 12, 2013 by DT in Mathematics.
