We discussed what happens to y = (1 + 1/x)^x as the values of x get larger and larger. We did calculations using the TI-Nspire. We were able to relate to the definition of e as the limit as x goes to inifinity of (1 + 1/x)^x. This value is used as the base in the continuously compounded interest formula, A(t) = Pe^(rt). We did a couple of example together and showed where to find the e button on the calculator.
