Area In Exercises 81 and \(82,\) find the area of the region bounded by the graphs of the equations. Use a graphing utility to verify your result. $$y=\frac{\log _{4} x}{x}, y=0, x=1, x=5$$
Using Properties of Exponents In Exercises \(107-110\) , find the exact value of the expression. $$32^{1 / \ln 2}$$
In Exercises 73-75, verify the rule by differentiating. Let \(a>0.\) $$\int \frac{d u}{u \sqrt{u^{2}-a^{2}}}=\frac{1}{a} \operatorname{arcsec} \frac{|u|}{a}+C$$
In Exercises 61 and 62, find the particular solution of the differential equation that satisfies the initial condition. $$\begin{array}{l}{\frac{d y}{d x}=\frac{1}{\sqrt{4-x^{2}}}} \\\ {y(0)=\pi}\end{array}$$
Analyzing a Graph Consider the function \(f(x)=\frac{2}{1+e^{1 / x}}\) (a) Use a graphing utility to graph \(f .\) (b) Write a short paragraph explaining why the graph has a horizontal asymptote at \(y=1\) and why the function has a nonremovable discontinuity at \(x=0\) .
