The Limit? what's the limit?
Limits, I kind of get some limits but when I get to a limit that I dont understand I go crazy and feel like hitting my head to the wall.:( I knoow...
well so I think I do need help!!plzzzz
The ones that I kind of dont understand are in pg.95 #11,#13 and 14.
when the function has numbers and x's or y's I get it but when it has sin,cos,tan,etc. or e,int. I dont get it. that's the only problems that I am having problems with.
When someone explains me a problem detail by detail
I always understand it the first time. So I need help detail by detail.

Tips and Hints
Allllllrighttttttttt TRIG.
I think thig is all about the unit circle. The unit circle is easy. To know the unit circle from head to toe you have to know the firsr quadrant of the unit circle. The unit circle has 4 quadrants. I think you know why they call it quadrants.(well if you dont know is b-cuz the circle is divided in 4 quarters) like I Said if you learn the first one you should not have trouble in knowing the other three. Sin and Cos think as your (x,y) X is cos and Y is Si :)
I dont think trig. confuses me but if it confuses you I think I'm Pretty good in the unit circle. Have any Q's feel free to ask me.

Inverse and Logarithm????
well need help...
I kind of know inverse one of the examples for inverse would be
Inverse of f(x)=2x is log2x you cant plug the x on top of the 2 but x supposed to be on top of the 2 and in the log, the 2 in the bottom of log and the x is in top of the blog. sorryyyyy..hope you understand it.
but I still have trouble graphing logarithms
Help help.!!!!

Even and Odd!!!!!!!!!!
Ok so basecally when a function is even that means that f(-x)has to be=to f(x). To prove that you are right about the function you plug your input and what ever you get from both they have to get the same to y-axis. In a graph on the top you cold see an real good example what ever you plug in (x) for example 1 the answer is 1 and if you plug in -1 you get 1 that's what I mean for even functions. Is the graph on the left.
Now Odd functions, well is just kind of like the opposite of even of course. But is the opposite down. Allright, this is the function for odd: f(x)= -f(x). This one is kind of weird yea I know.But if you understand it I will be easier. To get you started this is one of that will get you started (x,y) can only be (-x,-y).
Is the graph on the right.
If you did not understand none of this explanations and you think you could better understand in simple words just think like this even points have to be equal to the next side like left = right.
And odd teh points on the top have to be equal to the opposite bottom side. like rigth top = left bottom. :)
