Exercise 9: Write down a limit expression to express mathematically the sentiment of each sentence below. 71' (a) As x gets larger and larger, the values of tangent inverse of x approach 5 7r (b) As x gets more and more negative, the values of tangent inverse of x approach 7 5. Exercise 10: Using Exercise 9 as inspiration and thinking about what the values of inverse tangent approach when the inputs do various things, evaluate each limit below. Do NOT use a calculator or graph. Use your brain and logic! You'll want to understand the behavior of the inner function before trying to gure out the overall limit. (a) lim tan1&4\") 3}00 (b) lim tanWear) IlOO (c) lim arctan3+ ac 3 (d) lim sin(tan_1 at) 1}00
