Selected answers to common questions:     Chain rule.     Maximizing the volume of a box.     Maximizing the volume of a cylinder.     Volume of a tank.     What is a derivative? Best Fit Quadratic Curve [02/21/2002] Given a scatter plot of X and Y cordinates, find the best-fitting quadratic curve. Big O: 2 Functions Map from N to N+ [6/25/1996] If f, g: N -> N+, then either f(x) is O(g(x)) or g(x) is O(f(x)). Why? Brackets or Parentheses? [01/07/1997] When using interval notation to describe when a function is increasing and decreasing, how do I know whether to use brackets or parentheses? A Brief Overview of Calculus [01/16/2001] I am required to take a calculus course, but I have no experience with it. What should I concentrate on? Calculate the Derivative for Sqrt(x^5) [03/09/2003] Why does the calculator fail when I calculate the derivative for sqrt(x^5)? Calculating Any Root [10/13/1997] I need to find an algorithm to determine any root of a number. I was told I could determine the estimated value by using Newton's Method... Calculating the Shortest Flight Path [10/30/1997] Is this spherical trigonometry or can it be solved using simpler geometric equations? Calculus (Area of a Plane Region) [5/20/1996] Problem: y = 4-x2 ; x axis - a) Draw a figure showing the region and a rectangular element of area; b) express the area of the region as the limit of a Riemann sum; c) find the limit in part b by evaluating a definite integral by the second fundamental theorem of the calculus. Calculus Constants [11/16/1994] If a "u substitution" is made for different parts of the function, I get different answers. However the back of my book says that only one of the answers is correct. Here is the problem: Integral of secant squared of 3x times tangent of 3x. Calculus - limits [12/10/1995] Find all the discontinuities of the following function and label those that are removable... Calculus: Limits [11/24/1997] Why does my textbook define the limit of (1/x) as x approaches zero as infinity? Calculus (Minimizing Volume) [5/13/1996] The arch y=sin x,0 less than or = to x less than or = to pi, is revolved around the line y=c to generate a solid. Find the value of c that minimizes the volume. Calculus of Piecewise Functions [06/07/2003] Can I take the integral or derivative of a piecewise function like the floor function [u] or the absolute value function |u| and still notate it in concise form, |U| or [U]? Calculus Problem Using Taylor Series [2/16/1996] Looking at the equation: 1 + x*2^(x-1) A Calculus Question [02/09/1998] I figured this worked out to -1/2: lim (x - (x^2 + x)^(1/2)) (x going to infinity). Calculus Questions [1/27/1995] A student from Riverdale has interesting integration questions. Calculus: Rate of Change in Volume [07/27/1997] The radius of a right circular cylinder is decreasing at the rate of 4 feet per minute, while the height is increasing at the rate of 2 feet per minute. Find the rate of change in the volume when the radius is 2 feet and the height is 6 feet. Calculus - Shell or Washer Method? [08/23/1997] I have a question regarding how to set up integrals for the volume of revolution. Calculus Starting Points [10/23/2001] I want to learn calculus because I have heard that it is important for applied math in engineering and I want to be an engineer. What should I learn, and in what order? Calculus Word Problems [04/03/1997] Minimizing functions and costs. Can dy/dx Be Treated as a Fraction? [08/26/2004] I learned that dy/dx was a notation that implied 'derivative of y with respect to x.' But in some calculus work, dy and dx seem to have individual meanings and dy/dx is treated as a fraction. How is this possible? Can f'(-1) Equal Zero and f''(-1) Not Equal Zero? [03/23/2004] Is it possible to have a derivative of zero and then have a double derivative that is not zero at that same x value? How? Carbon Dating the Shroud of Turin [05/16/2000] In 1988, scientists found that the Shroud of Turin contained 91% of the amount of carbon-14 contained in freshly made cloth of the same material. How old is the Shroud according to the data? Cardan's Cubic Method [7/19/1996] Cardan's well known formula solution of cubic equation x^3 - 3x^2 - x - Sqrt[2] = 0 gives us a single "monstrous" algebraic real root which appears to defy further simplification.... Cases Where the Newton-Raphson Method Fails [06/30/2005] Why does the Newton-Raphson method work for some functions but not for others? Catenary Curve [03/30/1999] Find the vertex of a catenary curve. Cauchy Principal Value Integral [09/17/2002] Why isn't an integral from negative infinity to positive infinity defined as the limit as t (or any other variable) approaches infinity of the integral from -t to t? Center of Mass [02/22/1999] Find the center of mass of a thin plate of constant density covering the region bounded by the parabolas y = 2x^2-4x and y = 2x-x^2.

Chain Rule and Product Rule: Differentiating [02/19/1998] Why isn't the result what I expect when I use the Chain Rule and the Product Rule to differentiate? Chain Rule Applied to Exponential Functions [10/11/2004] How do I use the Chain Rule to find the derivative of a function such as f(t) = 27 e^(-.14t)?

Cola Consumption [05/03/1999] The rate of consumption of Cola in the U.S. is S(t)= Ce^kt where S is measured in billions of gallons per year and t is measured in years from the beginning of 1980...
