Chapter 1, Problem 125(choose chapter or problem)
Graphical Reasoning Consider \(f(x)=\frac{\sec x-1}{x^{2}}\).
(a) Find the domain of f
(b) Use a graphing utility to graph f. Is the domain of f obvious from the graph? If not, explain.
(c) Use the graph of f to approximate \(\lim \limits_{x \rightarrow 0} f(x)\).
(d) Confirm your answer to part (c) analytically.
Text Transcription:
f(x) = sec x - 1 / x^2
lim_x rightarrow 0 f(x)
