Today we looked at the example of a bouncing ball example 6 section 4.4 - this was an example of an "exponential" expression HW includes an application of this idea to a compound interest question. We then looked at "Sum to Infinity" = a/(1-r) provided that the absolute value of r is less than 1. HW includes a question relating this to recurring decimals.

Today we reviewed geometric sequences looking at example 5 from section 4.4. We then introduced the sum of terms of a geometric series example 1 and 2 from section 4.5. We also learned how to use the 'log' function on the calculator to evaluate powers of given bases that give a particular solution. 

HW is Exercise 4.5 Q.4-7
