april 10th

Well today was a work class so there isnt much to say about the class. For one thing remember that 45 objectives are due by friday. Since i am supposed to put something useful on here i figured i might as well show everyone a trick Mr.Max showed me for a question on objective 37/38.

The question is :

Find the product (1-(1/2))(1-(1/3))(1-(1/4))....(1-(1/96))

Well it is simpler then it looks!!!

First: 1-(1/2)=1/2

1-(1/3)=2/3

1-(1/4)=3/4




If you didnt notice there is a pattern (1/2) x (2/3) x (3/4) x (4/5)...and it keeps going all the way to 1-(1/96) which equals 95/96. You can just eliminate the numbers all the way from the start of the question to the end so it everything gets cancelled out except for 1 on the top and 96 on the bottom. So the answer is 1/96.

If it is explained well enough then you can jsut ask me in person but i tryed my best to do it on here so i hope it helps.
