Colleges

1. 3 Majors

- Ethics major: Ethics majors study the concept of moral good and practice applying it in various situations. They examine the history and theory of ethics as well as various belief systems. It is determining what is good and wrong and why a religion may think it is good or bad.

- Business major in Marketing Research: Students of marketing research study people’s buying habits in preparation for business careers. They learn how to conduct surveys, research buying trends, study the competition, explore advertising campaigns, and more. I am interested in this because businesses bloom when a certain fad is in and businesses can also break when a fad is gone.

- Community Psychology Major: Community psychology majors learn how to use psychological concepts to study social problems and explore possible solutions. Courses cover such topics as large-group counseling, the prevention of social problems, and social change.

2. Colleges:

- USC- For the ethics major, the closest college is USC, i dislike USC because i like UCLA, but since USC is the closest, I would go there for an ethics major. Good thing i still don't know what i wanna be when i get older. The minimum GPA is atleast a 3.0.

- Boston University offers a marketing research business major. It takes atleast a 3.0 to get into the college. I would like to go out of state for college, since I want to see the world. On my GPA, 35% of students get accepted.

- University of Washington, Bothwell, offers a community psychology degree. It is a 4- year public university that offers a bachelor and master's degree in this field. It is only 7% hispanic, so my ethnicity may help me get into this college.

NOTE: Thanks to this blog activity, I have gained somewhat more of an idea on what I wanna study when it comes to choosing a university.

My hints and tips

Transformations

The way i remember transformations is that they are counter intuitive. Usually the negative sign would mean shift x numbers of units to the left, but when it is in parenthesis, it means that u have to move it to the right. It usually means the opposite of what you think is right. When it is not in parenthesis, negative means down and positive means up.

ex. f(x-4) would mean that you have to shift the graph 4 units to the right.
ex. f(x)-4 would mean that you have to shift the graph 4 units down.

Trigonometry

The way I see trigonometry is by using my unit circle. I have memorized the unit circle from left to right and up to down. I know it pretty well now, it's just that when i have to draw it under pressure, i overthink things. =[
Well, the way i remember, it is that i remember the first quadrants, then i just mirror it from right to left, left to down, then left to right. The radians mirror, so it is, pi,pi/6,pi/4,pi/3,pi/2... from there it is mirrored. The first quadrant is positive, the second is negative positive, the third is all negative, and the fourth is positive negative. The quadrants are pretty easy, but the coordinates are a bit hard. It is kind of the same thing just different numbers, the zeros are pretty easy, its (1,0), (0,1), (-1,0), and (0,-1). The other coordinates are: (root of 3/2, 1/2), (root of 2/root of 2), then it is (1/2, root of 3/2). Then it is mirrored the same way.

What worries me?

Well, I need help on how to graph sin and cosine. I need to study the graphs more because I struggle through them. I also need help on finding the zeros of a graph. Any hints and tips would help me out... =]

Inverses and Logs

I learned this week that logs are exponential functions. A log always has a base of ten unless it has another base on it. A log can be used to find the square root of a number or the exponent of a number. The root of the number goes on the bottom as the base.
ex. Log2(4)=2
2 goes on the bottom as the base.

ln is the natural log. ln is basically the log of e. e is about 2.71, it is a value like pie. Using logs can help us graph equations and figure out exponential functions.

This week we also learned about functions and their inverses.
The inverse of f(x)=f^-1(x). To make sure an inverse is the inverse of the function, you use this equation.
(f o f^-1)=x & (f^-1 o f )=x.
If the number does not fit the equation, it is not the inverse.
The inverse of x^2 is the root of x.

questions: the main question i have is how to find the inverse by solving it.

Even: to find out if a function is even, you first have to use the equation, f(-x)=F(x). The equation will tell you if the function is symmetrical about the Y-axis. Quadrant 1 and 2 will be reflected on one another.

Odd: to find out whether or not a function is odd, you first have to use this equation, f(-x)=-f(x). The function should be symmetrical about the origin of the graph. It would be reflected from quadrant 1 to the x and y axis.
