Use a graphing utility to graph the function. Use the graph to determine the behavior of the function as \(x \rightarrow c\) (a) \(x \rightarrow\left(\frac{\pi}{2}\right)^{+}\) (b) \(x \rightarrow\left(\frac{\pi}{2}\right)^{-}\) (c) \(x \rightarrow\left(-\frac{\pi}{2}\right)^{+}\) (d) \(x \rightarrow\left(-\frac{\pi}{2}\right)^{-}\) $$f(x)=\sec x$$
Find a model for simple harmonic motion satisfying the specified conditions. Displacement \((t=0)\) 3 inches Amplitude 3 inches Period 1.5 seconds
Use a graphing utility to graph the function and the damping factor of the function in the same viewing window. Describe the behavior of the function as \(x\) increases without bound. $$y=\frac{4}{x}+\sin 2 x, \quad x>0$$
Complete the equation.
$$\arccos \frac{x-2}{2}=\arctan (\text{_____}), \quad 2
