Muddiest Point.

This unit went really slow and dry. Before the break I was doing fine but after the break I basically forgot all the rules for solving and simplifying.

Muddiest Points are:

*Word Problems - Hard to analyze and use data in an equation

*Factoring - Factoring tougher trinomials.

November 20 Pre-Test

Today we had a Pre-Test, these are some the concepts that was included in the Pre-Test.

Rational Numbers

*Can be written as a fraction

*Fractions
*Whole Numbers

*Mixed Numbers

*Decimals that end.

*Decimals With a Pattern.

Irrational Number
*Cannot be written as a Fraction
*Decimals with no end/repeating/pattern.


Radical Operations:
Adding/Subtracting:

When you have the same radicand/ike terms, you just simply add them together.

For Example:





---------------------------------------------------------------------------------------
When both radicands does not have the same value you might consider factoring the number so it can have the same value.

For Example:


------------------------------------------------------------------------------------------
*When a problem has same radicand but does not have the same root, you cannot add them together because they are not like terms.

For Example:



______________________________________________________________

Multiplying:

Dont forget to use FOIL whe multiplying.



---------------------------------------------------------------------------------------
Be careful when subtracting after multiplying! Only add the like terms.
Also don't forget that there's always a one before the root.

____________________________________________________

Rationalizing
The denominator is a sum of 3+√y, so we multiply numerator and denominator by the difference 3 - √y.

------------------------------------------------------------------------------------
The denominator is a difference of √7 - √5, so we multiply numerator and denominator by the sum √7 - √5



The test is on Monday, so be ready for it.

The next Scribe is ARJEL......

Personal Muddiest Point

My muddiest point are:
*Not knowing when to use negative or positive when rationalizing.
*Word Problems (The whole back of the Pre-test!!)
*Help with some of the Vocabulary.

Where I Am In Pre-Cal

Factoring and Polynomials - Not really understanding all of the concepts.
Analytic Geometry - Do not get the some of the unit but understand the distance, slope, etc.  
Trigonometry - Pretty Good
Radical and Exponent - Getting it but not all!

Today Ms. Eviatar went over the questions that students were having trouble on. She also showed us that the tan of one of the angle is equivalent to the slope.

Here is the activity that we did just in case you missed it.

Just don't forget that .
