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?
