find the length of the curve calculator

Then, for $i=1,2,,n,$ construct a line segment from the point $(x_{i1},f(x_{i1}))$ to the point $(x_i,f(x_i))$. We have $ f(x)=2x,$ so $ [f(x)]^2=4x^2.$ Then the arc length is given by, \[\begin{align*} \text{Arc Length} &=^b_a\sqrt{1+[f(x)]^2}\,dx \\[4pt] &=^3_1\sqrt{1+4x^2}\,dx. Dont forget to change the limits of integration. Thus, \[ \begin{align*} \text{Arc Length} &=^1_0\sqrt{1+9x}dx \\[4pt] =\dfrac{1}{9}^1_0\sqrt{1+9x}9dx \\[4pt] &= \dfrac{1}{9}^{10}_1\sqrt{u}du \\[4pt] &=\dfrac{1}{9}\dfrac{2}{3}u^{3/2}^{10}_1 =\dfrac{2}{27}[10\sqrt{10}1] \\[4pt] &2.268units. If we want to find the arc length of the graph of a function of $y$, we can repeat the same process, except we partition the y-axis instead of the x-axis. Many real-world applications involve arc length. find the exact area of the surface obtained by rotating the curve about the x-axis calculator. A piece of a cone like this is called a frustum of a cone. Here, we require $ f(x)$ to be differentiable, and furthermore we require its derivative, $ f(x),$ to be continuous.

The concepts we used to find the arc length of a curve can be extended to find the surface area of a surface of revolution. Furthermore, since$f(x)$ is continuous, by the Intermediate Value Theorem, there is a point $x^{**}_i[x_{i1},x[i]$ such that $f(x^{**}_i)=(1/2)[f(xi1)+f(xi)], \[S=2f(x^{**}_i)x\sqrt{1+(f(x^_i))^2}.\nonumber \], Then the approximate surface area of the whole surface of revolution is given by, \[\text{Surface Area} \sum_{i=1}^n2f(x^{**}_i)x\sqrt{1+(f(x^_i))^2}.\nonumber \]. In this section, we use definite integrals to find the arc length of a curve. What is the arc length of #f(x)= 1/x # on #x in [1,2] #?
