Exercise 2.4

Choose a random $x$ and compute $(\exp x) * (\exp (- x))$ with a spreadsheet. What do you get? How about $(\exp 3 x) * {(\exp (- x))}^{3}$ ?

Solution for $(\exp x) * (\exp (- x))$ :

My random choices are 1 and 3. For 1, I get $\exp 1 = 2.718281828$ , $\exp (- 1) = 0.367879441$ , and product 1. For $x = 3$ , I get $\exp 3 = 20.08553692$ , $\exp (- 3) = 0.049787068$ and the same product.

Solution for $(\exp 3 x) * {(\exp (- x))}^{3}$ :

I find, for $x = 1$ , the answer 1. You try something.
