7.38The length of the longest ladder that can negotiate the corner depicted in Fig. P7.38 can be determined by computing the value of that minimizes the following function: W2 sin , sin(--8) For the case where wi- w22 m, use a numerical method described in this chapter (including MATLAB's built-iin capabilities) to develop a plot of L versus a range of 's from 45 to 135
