lim x 2 tan x sec x
Chapter 8, Problem 90(choose chapter or problem)
Analytical Approach In Exercises 89 and 90, (a) explain why L’Hôpital’s Rule cannot be used to find the limit, (b) find the limit analytically, and (c) use a graphing utility to graph the function and approximate the limit from the graph. Compare the result with that in part (b).
\(\lim _{x \rightarrow \pi / 2^{-}} \frac{\tan x}{\sec x}\)
Text Transcription:
lim _x rightarrow pi / 2^- tan x /sec x
