This exercise is about limits and vertical asymptotes. The graph of the function f(I) 1 - cos(21) sin (21) cot (I) - was plotted on the software Maple", and the result is shown in the image below. Use the limits tool of WolframAlpha ( https://www.wolframalpha.com/examples/Limits.html ) to compute 1 - cos (21) I id sin (27) cot (I) with different values of a. Then answer: Among the vertical lines below, which one is a vertical asymptote of the graph of f? Select one: The line I = 3.14. The line I = 7 The line I = 1. O The line I = 0. The line I = 2 O The line I = $- The line I = 1.57 The graph of f does not have any vertical asymptote. The line I = 1.5 The line I = 10 O The line I = Check
