    Curve sketching

    it dosent. At all forget about the y=3x, its meaningless. To find the curvature of the graph, you take 1st and 2nd derivate. Itll get you x>0, and x>0, hence it concaves upwards. Look at the link the Cazic posted.

    Graphs

    Did you figure this out yourself or was it taught at school or smthing?

    Graphs

    Well thats the question and you guessed it. But is it really like that. Cause it said define g(x) as.... and i was assuming a little more algebra.

    Curve sketching

    there is no y=3x asymptote. Ive got confused. There is no horizontal tangent. Just a tangent as x>>0 of y=3x. Basically, at the origin, the curve melts into the tangent. If you graph this, the curve actually goes away from the y=3x.

    Curve sketching

    Actually, your getting confused between oblique asymptotes and horizontal tangent. As the curve approaches zeor, dy/dx >>>3. Therefore a horizontal tangent of y=3x exist. Oblique isotopes are something altogether. It occurs with large x, and y approaching an asymptote that is not the...

    Curve sketching

    I dont think oblique would be 3x. You sure? y=3x + x^(3/2) as x >> inf y inf as well?

    Graphs

    I guess this is sort of 3 unit stuff. Two questiions Given that f(x) is odd and has an inverse which is also a functio, show that f^-1(x) is also odd. Second Given any function f(x), define g(x) = 1/2 (f(x) + f(-x)) and h(x) = 1/2(f(x)-f(-x))

    Question to all gay people out there

    The first signs of turning gay are questions on how one discovers he/her true sexual nature. The expression are vast and varied from talking about it with gay friends to posting a thread on how you know your gay.

    Values for Frankenstein vs Bladerunner

    o jeez, i didnt want a generic sentence lolz I mean, would science for FR's context be seen as a value? What about commerce in Scott's time?

    What have YOU done so far?

    Man, this is ridiculous. You guys all done so much. Ive only done some math and bio, and thats about it... shame:(

    Sequence and seriesssss

    ooo i see. I thought it meant arithmetic progression but how can b be a geometric mean?

    Sequence and seriesssss

    Is this step neccessary? Can we just state that a = log2a and d = log2r since, its in the form of a+(n-1)d? What does b is the AM of a and c mean?

    Values for Frankenstein vs Bladerunner

    Now it is generally understood that each context of the texts, was dominated by science (frankenstein) and commerce (br). Could we say that these were the values of each context at their time?

    them Sydney Trains moments

    Re: them cityrail moments It was peak hour and the carriage was packed. I was standing next to the bar near the gates and this giant british guy was towering over me. We were like side by side. Everytime he would reach out to the bar for grip, i would literally smell his armpits, and it was...
