SL Math Chapter 6 Test
Hey guys!We just finished our SL Math Chapter 6 test today! This chapter taught us about arithmetic and geometric sequences and series. In other words, we discovered the equations defining sequences such as 2, 4, 6, 8, 10 and 2, 4, 8, 16, 32. As you might be able to tell, the first sequence mentioned is arithmetic since you must add to get the following number. The second sequence is consequently geometric since you must multiply. In the last section of the chapter, we looked at infinitely converging geometric sequences. For example, add together all the numbers in the sequence 2, 1, ½, ¼, ⅛... It gets infinitely closer to 4 but never reaches it.
An example of a sequence!
The best thing about the tests we're taking is how they're structured! Our math teacher takes previous problems from the exam and arranges them into Papers 1 and 2! We must also follow IB rules by not using a calculator on the first paper. This setup is for our benefit since it helps us to prepare for our actual test in May of 2016!
