Algebra VS Calculus the BIG fight
2) Both the slope and derivative use the change in y/ the change in x formula but for the slope their is no lim unlike the derivitive where the lim is when h->0 so the difference in the equation would be lim h->0 f(2+h)-f(2)/h where h is how many point away from the initial point. Also a slope would the slope (obviously) of a specific line where a derivative would be involved with Tangent lines of curves.
This is what I got probably very arguable but eh screw it I tried...

What's my limit?
2) The other types of problems that I have trouble with are the problems with fractions in fractions. For instance, [(1/x+1)+(1/2x)]/x these types of problems get me stumble because I forget how to simplify the problem. Then the same thing about plugging in the limit especially when it is zero...damn zeroes.
3) Int type problems just stumble me. I know how they look but I can't graph them without using the calculator and I really do not know how to find the limit at all I try but fail HELP!!!

Toga College Party WOOOOOH
1) -General Engineering- Associate’s degree level provides solid preparation for any type of engineering degree at the bachelor’s level and if one continues to get their degree in this field they get more education on different type of engineering and business. Also use your invention in a field that has nothing to do with engineering.
-Psychology- Well modern psychologist do what the ancient Greeks do in which they study the mind by asking it questions (not literally...well kind of) asking these questions one learns why one acts a certain way, how one can deal with their struggles that placed in front of them, etc. A whole lot of "I'm in your mind" type stuff.
-Music Performance- As "kick back" of a class as one can get but that's not the reason I want it. This major allows one to practice their music to allow skill to develop. Also in this process one will have to come up with their own sound that signifies them.
2) -MIT- Best Math school, including Engineering, there is. Have been banned from certain competition due to the fact that they keep winning them. Also it is a private 4 year that only 12% of people get in who want to get in. They offer a Bachelor's, Master's, and Doctoral
-University of California: Berkeley- Public 4 year university that offers Bachelor's, Master's, Doctoral, and First Professional. 22% of people who apply get in.
-University of the Arts- This is a private 4 year university.Offer Bachelor's and Master's degree. Only 8% of their students who got in had a 3.75 GPA in HS...Wow I thought it would be higher woohoo i can probably get in.
Note: Going to college seems challenging but oh well time to step it up I guess

Silly teacher, TRIGS are for students
2)Well the unit circle itself is difficult but possible. One tip the was useful for me is that it goes in a pattern 6,4,3,2 then on the second quadrant it goes 3,4,6,2 then the third quadrant is 6,4,3,2 the fourth quadrant is 3,4,6,2 pretty simple some times. now knowing pi is kind of simple first quadrant they are all pi second quadrant pi is -1 of the denominator third is +1 of the denominator fourth quadrant is x2-1 of the denominator. The coordinates go (3/2, 1/2), (2/2, 2/2), (1/2, 3/2) now the order of the these coordinates are the same as pi but they follow the quadrant rules Q1(+,+) Q2(-,+) Q3(-,-) Q4(+,-). Now Cos=x Sin=y simple so Tan is Sin/Cos so it is y/x Csc and Sec are difficult for me but I found out a way to remind myself of how to tell the difference of the two, ok so the first letter is the opposite of what it is(ok I kind of confused myself but what I mean is this Csc is 1/Sin, Sec is 1/Cos see C=S and S=C). Cot is simple it is just the opposite of Tan so it is Cos/Sin, x/y. Simple kind of.
3)Ok now what confuses me is how to graph these things. I forget where they start where is the period, etc. I'm just terrible with them and that really sucks I don't remember how to graph the inverse. AAHHHHHHH this is just bothers me so much I need to remember but i get confused help!!!

Inverse and Logarithms
I didn't understand what exactly to do when trying to get y by itself when you involve an ln or e . though i know they cancel sometimes I don't know exactly what to to when dividing or multiplying them to both sides.

Even and Odd FUNctions
Note:Would be a lot easier to prove if I new how put in pictures but oh well.
An odd function,f(-x)=-f(x), is when a graph is rotated 180 degrees and it still maintains the same graph thus saying that if one chooses a point from the graph then its opposite (x,y) are on the same graph. For in stance lets assume that a graph has the point (1,1) then the point (-1,-1) is on the same graph. An example is the equation f(x)=x it is just a diagnal line that hold the point (1,1) and various others, now when rotated it is still the same line and still hold the same point including,which it always included, the point (-1,-1) and other point that are opposite of the same point.
Note: This is as simple as I can put it and I can barely understand it but again it would be a lot better if I new how to put in pictures.
