X=C

1. The difference between finding the limit of a function as x=c and pluging in x=c is that finding the limit at x=c your finding a coordinate as you approach x from both sides. meaning it doesn't exist so ur trying to get as close as possible to get an answer. there has to be a domain issue.. i think
just plugging x=c to the function, that is the answer. because it actually exists.

2.the similarities between finding the slope and the derivative is nothing because they are the SAME. your finding the SLOPE. the difference between them is the derivative is finding the slope of the tangent line in that function the slope is the slope .

I HATE Limits :)

First of all what are limits ? what are they used for? Why are they the base of all calculus.
When Ms.Hwang Talks about limits i blank out because its like she is speaking another language.

There are simple problems like

f(x)= lim(x►1) (x^2-1)/(x-1)

1.First you foil out (x^2-1)

(x-1)(x+1)/(x-1)

2. Then the (x-1) on top and bottom cancel out and become 1.

(not ZERO)

3. Last you plug in the number that is with the limit to see if the limit exists.


(x+1) = 1+1 = 2

The limit is 2.


Another thing i dont know how to do is foiling out formulas like this


2x^2-5x-3

i was never taught that!!! I think???

so that is about it.

College 101

Majors

1. Health Professions and Related Clinical Science

3. Animal Sciences

Animal Care Technician- Learn how to care for animals how their nutrition should be, their behavior and how the bond with a human companion.



Colleges

1.University of California: Los Angeles
-The mission of the medical education program of the David Geffen School of Medicine at UCLA is to prepare graduates for distinguished carrers in clinical practice, teaching, research, and public service.
-They dont have photogrphy as a class. = (
-Very big campus (judging by pictures and map)
2. University of California, Santa Barbara
- Surrounded by a lot of Water!

The websites were really hard to find what i wanted but i am also interested in schools with culinary art majors in california as well. I found The Art Institute Of California but i want a school that has both Medicine And cooking in it, but mostly Medicine.

Tips and Hints!

1. What i remember about transformations?

Dont know how to eplain it very well but this is how i remember.
(Here is a website that may help, Look For Tutorial #31 or 32)
http://www.wtamu.edu/academic/anns/mps/math/mathlab/col_algebra/index.htm

Example.
f(x) = (x^2 +3)-3

a) The first thing i do is identify what the original function was.

Linear Function Domain: Range:

Constant Function Domain: Range:

Quadratic Function Domain: Range:

Cubic Function Domain: Range:

Square Root Function Domain: Range:

Absolute Value Function Domain: Range: The function is a parabola because of the x^2 (one input gives you 2 outputs)

b) Once i know what the original function was, Then i look for parentheses in the function.

The function does have parentheses.

f(x)= (x^2+3)-3

(For me, this means that there will be a horizontal shift (the function will go left of Right)

--Because there is a positive 3 the function will shift Left 3 units

--If it were to be Negative the function will shift Right

c)Once i have shifted the function horizontally, I look at the Function and see if there are any numbers outside the parentheses.

There is a number outside the parentheses.

f(x)= (x^2+3) -3

(The number outside makes the function shift vertically up or down)

---Since there is a negative 3, it will shift Down 2 units

---If the number were to be Positive, it will Shift Up

-------------------------------------------------------------------------
2. What i remember about Trig And Understand?

Trigonometry is about Triangles!!!



This is how all the The circle works. With the Functions.
Each Function being describe is what we are looking for when it comes to the Unit Circle and the Functions

This website Can help you understand more!!!
ITS CRAZY!!!

3.What i Dont unserstand?

I have trouble with unit circle and coming up with cordinates on the spot. Like if someone asks me to tell them quickly the cordinate. But thats just me and remembering things = D I think thats it.

Logs and Inverses

Well from what Ms. Hwang told me LOGS ARE EXPONENTS!!

I don't know how to explain it but i just get them.

Example 1
log₂ 16=x

-This equation is read Log base 2 of 16 equals x.

2^x=16

-Your trying to find 2 to What input will be the Exponent that will give you an output of 16.

Answer:

X=4


Why?

2 to the power of 4, equals 16


log_ax means the power that you raise

a to in order to

get x
------------------------------------------------------------------------

Inverses
--------------------------

The way i find the inverse of a function is by plugging in x for y.


For example
--------------------------
f(x)= 2x+3

y=2x+3
1. Switch the variables x and y.

x=2y+3
2. Subtract 3 from both sides.

2y=x-3
3. Divide both side by 2.

y=x-3/2
4. This is the Inverse.


what i dont understand are how ln can be the inverse of e.
If e is 2.71.... then what is ln.

1/2.71...... if there was a simple way to understand this i would probably not get lost....

HELP!!!

EVEN and ODD functions

Even Functions: An even function is when the function is symmetric about the y-axis.

The right side is mirror image of left hand side and the left side is mirror image of right hand side.

Mathematically speaking, if you plug in a (-x) in the place of a (x) you will get the same output.

For example: f(x) =7x² + 10

So I'll plug –x in for x, and simplify:

f(–x) =7(–x)² + 10
= 7(x²) + 10

= 7x² +10

--------------------------------------------------------------------------------

Odd Functions: An odd function is when a function is turned about, on it's origin, 180 degrees.



For example: f(x) = 6x³ – 3x

so I'll plug –x in for x, and simplify:

f(–x) = 6(–x)³ – 3(–x)
= 6(–x³) + 3x
= –6x³ + 3x

<To make it easy for me, I think of multiplying through the function by -1 >


This picture is a perfect example of what the 180 degrees turn on the origin looks like.

My Happy and Sad Halloween

October 31, 2009

I had my Rop class when the day started and went on a RIDE ALONG with one of the animal control officers and we rescued a cute 10 week old Doberman dog. She was sweet. she was hit in the freeway and had a fractued leg = ( we took her back of to the shelter to take care of her and hope she gets adopted . She will be a 3 legged dog but she is a sweetheart!!! The officer took a picture of the dog and gave me it .

After the class i came home and got ready to got to the LA Clippers vs. Dallas Mavericks game with the clippers losing. = ( oh well. Gordon (#10) wasn't on his game. 84 to 93.

Poly HOMECOMING!!!

October 30, 2009


i HAD A REALLY BUSY DAY THIS DAY!!! i Started with the HOMECOMING Pep Rally.




the pep rally went great with all of its performances. i had to take pictures of the pep rally like this one of our principal Mr. Lorera he looks funny ut in the spirit!!!







right after this pep rally the day went on till the parade. Where JUNIOR COUNCIL WON THE FLOAT CONTEST!!!

THESE PICTURES TURNED OUT GREAT(I TOOK THEM!!!)THERE WAS FIRE WORKS AND EVERYTHING AND the long day ended with us WINNING THE HOMECOMING GAME!!!!

A Million Words...

My name is Monica.
I have loved math since 3rd grade, from what I remember and have done really well in school. remembering formulas is sometimes difficult but if i use them frequently, i usually remember. I strive for an A all the time. I get lost most of the time but over all I understand the material.^_^

I love animals. My favorite type of dog is a Great Dane. I'm currently in an ROP class that helps me learn how to care for a variety of animals at an animal shelter. Most times its sad because there are a lot of animals that don't get adopted.

Hopefully i get an A in this class!!!
