April 9th

Fellow Classmates,

Well as I am sure you all have noticed, Mr Max is not present again today. I saw him briefly before class and he said the test is STILL ON for tomorrow.

Key points to remember while studying for the test...
5log(x^4) - 6log(x) - MAKE SURE YOU DIVIDE WHEN SUBTRACTION IS USED!
answer: 30 log ((x^4)/x)

5log(x^4) + 6log(x) - REMEMBER TO MULTIPLY WHEN ADDITION IS BEING USED!
answer: 30 log (x^4)(x)

Good luck on the test tomorrow..
Accelerated Math deadline next Friday - 30 objectives!

Thanks,
Cramer

P.S. Keep your elbows off the table

Not Much...

Very little (read: nothing) happened in the way of instruction on my scribe day so unfortunately I have very little to write about for my blog post...

At any rate, here are a few interesting links:

This is simply a 3d logic game - just connect the squares. I thought it would be pertinent to our math glass since logic skills and mental three-dimensional rotation skills are closely related to mathematical aptitude.

Also for the more verbally inclined:

Just a simple vocabulary test, only with a little extra feature: for every word you get correct, the site will donate 20 grains of rice though the UN World Food Bank to help end world hunger.

Also for the budding autodidacts among us:

Change of Base

Well technically this was our last class before SPRING BREAK since tomorrow those of us who aren't cramming for accelerated math objectives will be cheering on cramer at team stuff day.

Anyways today he taught change of base theorem, which is needed when the base isn't 10. Below is the derivation of the formula you need( the thing in the box).

Then he showed us examples.. both with and without a calculator.


And then.. of course.. the dreaded HOMEWORK .

Also with regards to that last comment on dreaded homework.. i saw this on the news.. great idea if you ask me.. have a read...

Yes this is extremely late.. partly because i had trouble logging into blogger.. AGAIN.. nevertheless.. my apologies.. also tecnically this isn't the last class before spring break and we do not have team stuff day tomorrow.. sorry for those of you who might have got their hopes up... Anna..

Logarithm Laws

Greeting peers today in Mr. Max's dictatorship, I mean class, he started by trying to recruit more students for the national math competition on April 15.

After this largely unsuccessful attempt we dived head long into logarithm laws which are largely based on rules for exponents that we already should know.

Exercise 22 1-14 was assigned and don't forget about the 19 accelerated math objectives due on thursday

adding to Amy's post

So as you all know, today Mr. Max taught us about logs!



He began with explaining to us what a log was, and it is really just another type of notation that can be used to express things such as really big numbers and it is the inverse of an exponential function.



He also explained what the parts of a logarithmic function were.

In the function:

x = b^y --> x is the argument, b is the base, and y is the argument.



In the second screen shot, he then went on to show us how to write exponential funtions in logarithmic notation and vice versa.



In the third screen shot he showed us a logarithmic function that does not exist. This is because if you try to sub in a +2 for the x value you wont arrive at a -4 and if you sub in a -2 for x, you will end up with a +1/2

On the fouth and fifth slides he graphed examples of logarithmic functions, and on the following slide he gave us a list of 8 common log properties.



Exercise 20 #'s 1-12 and Exercise 21 #'s 1-8 are due for tomorrow!



Hope these notes were helpful and have a great day!

LOGs

Hello everyone. Today Mr. Max taught us about LOG's. We defined them and wrote some notes about the properties of LOG's. Here are the screenshots from today:

Seems like it won't be too terribly hard. He also reminded us that doing the cumulative excercises really does help.

He also gave us a game plan for the week:

Monday(today)-define LOG's

Tuesday-Law's of LOG's

Wednesday-Solving LOG's with theorems

Thursday-Natural LOG's("i")

Some notes about Thursday:

-Mr.Max is planning on teaching a lesson, so if you haven't signed up for "Team Stuff Day", DONT!

- 19 Objectives are due on Thursday at 3:40! Don't leave it till the last minute(like I tend to do...)

Well, since there will be more people than just me putting stuff up today, I'll keep it short and sweet. You can hear what they have to say. Later!
