Best ResponseYou've already chosen the best response.0\[\lim_{x\to \frac{\pi}{2}} \frac{\sin x}{x}\] What is the value that sin(x) assumes when x approaches pi/2 ? What is the value that x assumes when x approaches pi/2? (trivial) The limit of a ratio is the ratio of the limits \[\lim_{x \to \frac{\pi}{2}} \frac{\sin x}{x} = \frac{\lim_{x \to \frac{\pi}{2}} \sin x}{\lim_{x \to \frac{\pi}{2}} x}\] Can you complete the exercise?

Best ResponseYou've already chosen the best response.0That function is continuous everywhere except at x=0. That means this limit is calculated by plugging pi/2 into the function to get the answer directly.
