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?

Bound to Confuse [08/07/2017]
An adult wonders about the usefulness of the upper bound and lower bound theorems. After clarifying their scope, Doctor Peterson delves further into what conclusions these do allow, and what they do not.

Brackets or Parentheses? [01/07/1997]

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.

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.

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.
