Use a graphing utility to graph the function. Describe the behavior of the function as \(x\) approaches zero. $$ f(x)=\sin \frac{1}{x} $$
Graph the functions \(f\) and \(g\). Use the graphs to make a conjecture about the relationship between the functions. $$ f(x)=\sin x-\cos \left(x+\frac{\pi}{2}\right), \quad g(x)=2 \sin x $$
Consider the function given by \(f(x)=x-\cos x\) (a) Use a graphing utility to graph the function and verify that there exists a zero between 0 and 1 . Use the graph to approximate the zero. (b) Starting with \(x_{0}=1,\) generate a sequence \(x_{1}, x_{2},\) \(x_{3}, \ldots,\) where \(x_{n}=\cos \left(x_{n-1}\right) .\) For example, \(x_{0}=1\) $$ \begin{array}{l} x_{1}=\cos \left(x_{0}\right) \\ x_{2}=\cos \left(x_{1}\right) \\ x_{3}=\cos \left(x_{2}\right) \end{array} $$ \(\vdots\) What value does the sequence approach?
Evaluate the expression without using a calculator. $$ \arctan (-\sqrt{3}) $$
Use the graph of the function to determine whether the function is even, odd, or neither. Verify your answer algebraically. $$ g(x)=\csc x $$
