Thanks guys.

Chain Rule Question is Find the derivative of F(x)= 3 sq rt of x^3-1 First step I did was changing the Sq RT to (x^3-1)^3/2 Then I solved it by 3/2(X^3-1)^1/2*3X^2 Another problem very similar F(X)= 3 SQ RT of X^4+3x+2 Step 1 (X^4+3x+2)^3/2 Then 3/2(X^4+3x+2)*4x^3+3 I know how...

Another thing after thinking about it a bit more, when it says Graph it on [-4,4] does it mean that the F(x) equation has to to touch that point? If it does its continous? If it doesn't it does not exist?

Homework Statement Grapher: Graph each function on (-4,4), and identify the point(s) at which the function is not differentiable. Homework Equations Graph F(X) = (X^2-2x+1)^1/3 on [4,-4] and Identify any points of discontinuity. The Attempt at a Solution I plugged in the F(x)...

The question is Graph f(x)=X^3-3x. Does it have any high or low points? What about symmetry? Okay the problem I'm having is what formula to use with a ^3 on the X, my previous 2 problems I did by using the quad formula, those questions were f(x)= 2x^4+4x^2-1, and f(x)= 16x^2+4x-3...

Hey guys thanks for the information, I got the 89 durring the summer of 06, at that time I was working 65+ hours a week, and when school came I cut down but I did not have time to read the manual, my 07 spring sem I didn't take any math classes, I'm now looking into section by section, but I...

I got mine recently, I haven't used it as much, because I still have a TI-83, someone told me that with a 89 you can store equations, notes and it shows all of your work? Is that true, because I heard this from two different individual, and a third person told me that it doesn't show all of your...

our college offers chemistry 100 which is MODECULE/LIFE IN MODERN WORLD and i qualify for chem 121 which is general chemistry am i better off at taking chem 100 since i have never took chem before? or should i just take chem 121 which I'm qualified for?

hey guys thanks for the input, i really apreciate it, i bought the 89 today, i got it for 124 :smile:

well I'm a civil engineering major, and my uncle is an engineer also whenever he helps me out with tutoring he uses his ti-89 all the time and tells me to get it, cause i will need it eventually and i already gota ti-83, but he reccommended me getting a ti-89 instead

i don't need it that badly, but eventually i will need it in the future, i went there to check they got the same quantity and the same price for it, I am just going to check every week, meantime i can also save up money to get it

yah i was bargain hunting around also i saw the same range as you did, but walmart has like about 5-7 in stock, and i doubt it anyone will buy a TI-89, so should I just wait and check back every week to see if the price drops, or should just buy it right now?

is that a good deal? Not even opened, its on clearence at a local walmart near my house.

oh ok, yeah its general chemistry at a community college

so what advice do you guys have for me? besides studying,links? sources? thanks i would really apreciate it :smile:
