###### A. $\operatorname{Let} \alpha: I \rightarrow R^{3}$ be a curve of class $C^{0}$ (cf. Exercise 7 ). Use the approximation by polygons described in Exercise 8 to give a reasonable definition of arc length of $\alpha$ b. (A Nonrectifiable Curve.) The following example shows that, with any reasonable definition, the arc length of a $C^{0}$ curve in a closed interval may be unbounded. Let $\alpha:[0,1] \rightarrow R^{2}$ be given as $\alpha(t)=$ $(t, t \sin (\pi / t))$ if $t \neq 0,$ and $\alpha(0)=( a.$\operatorname{Let} \alpha: I \rightarrow R^{3}$be a curve of class$C^{0}$(cf.

The following example shows that, with any reasonable definition, the arc length of a$C^{0}$curve in a closed interval may be unbounded. Let$\alpha:[0,1] \rightarrow R^{2}$be given as$\alpha(t)=(t, t \sin (\pi / t))$if$t \neq 0,$and$\alpha(0)=(0,0) .$Show, geometrically, that the arc length of the portion of the curve corresponding to$1 /(n+1) \leqt \leq 1 / n$is at least$2 /\left(n+\frac{1}{2}\right) .$Use this to show that the length of the curve in the interval$1 / N \leq t \leq 1$is greater than$2 \sum_{n=1}^{N} 1 /(n+1)$and thus it tends to infinity as$N \rightarrow \infty$## Answers #### Similar Solved Questions 5 answers ##### UurquaticSedijian-pdlCISES FOR SFCTION 14 Ferkcs DX RulersHelhod I0 FItum Culm nzthu ~Iatt Hlrr Jep gncn iLal-vzke pbkm CXFt Ihe timc Eterval yecifidd Yotan5er' Jua AEEuAImalc YiLes ol Ilic dcprnkot variabk.
