    Your prism (actually right rectangular prism) consists of two 3 x 4 rectangles, two 3 x 9 rectangles, and two 4 x 9 rectangles. As long...

    i need help by understanding how to answer part b(ב) of the question: There is prism. 1.a.(א) write the measures of the rectnagle that...

    To be an inflection point, there must be a change in concavity. Neither the first derivative nor the second derivative has to exist at...

    It isn't always easy to visualize the second derivative, even from a very accurate graph, much less a "sketch". Here (red) is x^(5/3)...

    Thank you. So to clarify: If a curve flattens or straightens near a point, i normally assumed the second derivative was zero there (...

    apple2357 posted the thread Second derivative? in Calculus.
    The graphs of y=x^(5/3) has a point of inflection of x=0 and so does y=x^(7/3). The graphs look very similar. But the second...

    Which is why I think High School level geometry will lend itself to use in Trigonometry and thus to Calculus. This is my understanding...

    It is rather detailed and I'm making good progress. I'm just noticing some minor shortcomings that matter. Mostly in the chapter tests...

    It's not that there isn't a y-intercept, but that there is no need to write a 0 term in an equation. What we are doing here is...

    My question exactly. It's needlessly confusing to a someone early in the path.
  • King Friday
    So, the absence of the y intercept is to be interpreted as "0" To state it would be redundant?
  • Dr.Peterson
    Now that you've shown the source of your question, I hope my answer helps; but I'm a little surprised the course would not have included...
