    Identifying Points of Inflection: ABCDEFHJKL

    I see my mistake. I only have one submission left so I want to make sure that I'm correct. At point B the concavity changes from up to down. Also at H, it changes from concave down to concave up, but I know that B and H are not the only points because I attempted that solution earlier. Can...

    Identifying Points of Inflection: ABCDEFHJKL

    I'm supposed to identify the points of inflection in the following graph: I know the point of inflection is where concavity changes, and I keep getting stuck on one answer that is apparently not correct. I believe that the following points are points of inflection: ABCDEFHJKL A -...

    Understanding the Second Derivative

    Oh you're right... the point of inflection is point B. This obviously isn't the exact graph that was on the quiz but I tried to do a good depiction of it. I hope that B was the actual point of inflection.

    Understanding the Second Derivative

    I'm not sure that A is the correct answer, but it was what a lot of other people picked. And if I'm not mistaken, isn't the second derivative the point of inflection? I think A better fits that profile.

    Understanding the Second Derivative

    I'm having trouble thinking about the second derivative. I've been thinking of it as the rate of change of the rate of change, but that seems to have gotten me into some trouble. This is a quiz question that I had: http://i.imgur.com/WUMqY5C.jpg Ignore the first part, as it should read...

    Presumably simple logarithm equationt

    Homework Statement What value of x satisfies the equation: 6 \cdot e2x = 4x The Attempt at a Solution If I'm not mistaken, I can move the 6 to the superscripted part of e, resulting in: e12x = 4x And then I can take the natural log of both sides, resulting in: 12x = ln(4x) Assuming I...

    Precise Definition of a Limit, Example Clarification

    This isn't a homework problem. My textbook has an example for this subject and I'm having difficulty understanding it. I follow the example up until the point at which it says, "Notice that 0 < | x - 3 | < (0.1)/2 = 0.05, then " I don't understand why delta was substituted with (what...

    Properties of Logarithms, Division and Multiplication

    Nevermind... realized that I didn't bring the exponents out front.

    Properties of Logarithms, Division and Multiplication

    Homework Statement Express in terms of logarithms x, y, z or w. Problem: loga(x8w/y2z4) Homework Equations log(u/w) = log u - log w log(uw) = log u + log w The Attempt at a Solution Here are my attempts: As you can see, the answers are pretty similar. I'm assuming...

    Particle Distance/Velocity - Natural Logarithms

    I'm not sure why this response was so aggressive. Anyway, thanks Curious! I figured it out. I had initially considered the v0/a solution but discounted it because I didn't think I could input v0 in the submission box.

    Particle Distance/Velocity - Natural Logarithms

    Homework Statement I'm going to post an image due to the complex syntax in the problem... The Attempt at a Solution I'm not going to lie... I really have no idea where to even begin with this problem. Because it says total distance traveled by the particle, I'm assuming that the...

    Measuring Gas Mileage Efficiency in Using the A/C, Rolling the Windows Down

    I'm not using the template because this is a rather abstract question about the way to approach a scientific experiment. I'm beginning a science project in which I hope to define the speeds at which using an air conditioning unit becomes more efficient than rolling the windows down in a car...
