What is -infinity plus infinity?

Algebraic Integration of Standard Normal Distribution Function [02/11/1998]
I've tried inspection and partial integration and don't seem to get the right results - I wonder if this is a function whose integral cannot be solved algebraically?

Algebra, Limit and Derivative Problems [7/28/1996]
Let x+y=1 and x^3+y^3=19. What is the value of x^2 + y^2?... f(x) = sqrt(2x+4), find f'(x)... d(8x^3+8x^2+6x+1)/d(2x) = ...?

Alternate Forms of the Derivative Formula [10/06/2001]
Why does f'(a) = limit as x approaches a of [f(x)-f(a)]/(x-a), and how do you use this formula to find the derivative? I get confused about when to plug in x for a or a for x.

Alternating Harmonic Series [11/18/1997]
I am trying to find the proof for the sum of the alternating harmonic series. I did find out that it is ln(2), but please tell me why?

Analysis of Signs of Derivatives of an Inverse Function [06/22/2005]
Given a continuous function f with f'> 0 and f''< 0, can I conclude anything about the signs of the derivatives of g, which is the inverse function of f?

Analytic Integration Problem [7/13/1995]
Is it possible to integrate [exp(-zcosh(t)] dt analytically?

Analyzing a Function [05/19/1997]
Find the domain, intercepts, asymptotes, critical points, points of inflection, and graph of the function: y = 3x^4-4x^3-12x^2.

Another Grazing Cow [6/7/1995]
A man has a barn that is 20 ft by 10 ft. He tethers a cow to one corner of the outside of the barn using a 50-ft rope. What is the total area that the cow is capable of grazing?

Antiderivative [11/17/1994]
One of my friends has asked me to solve a problem for her. I arrived at the right answer using my method of doing it. Later, she showed me her method. It seems correct, too. I was just wondering if you can find a mistake for her. Question/answer: antiderivative of secant square 3X times tangent 3X= 1/6 (cos3X) to the negative 2 plus C.

AP Calculus - Minimizing Time Traveled [12/22/1998]
A person on a boat 9 km from the shore must go 12 km down the shoreline in the shortest time possible. Find a function for where the person should hit land...

AP Calculus - Minimums and Maximums [12/23/1998]
Hints for finding specified x-coordinates...

AP Calculus Test [8/24/1996]
Where can I find a site with information about the AP calculus test?

Applications of Imaginary Numbers [10/14/1997]
Where are imaginary numbers used today in real life, as in the work force or other areas that use math?

Applied Problems in Maxima and Minima [08/30/1997]
At what first quadrant point on the parabola y = 4 - x^2 does the tangent together with the coordinate axes determine a triangle of minimum area?

Arc Length Formula [07/28/1998]
Find the arc length of a curve in symbolic form and decimal approximation.

Arc Length of Sine Curve [7/18/1996]
What is the arc length of sin x from x = [0, 2pi]?

Area Between a Line and a Curve [11/5/1994]
A high school senior writes: "The horizontal line y=c intersects the curve y=2x-3x^3 in the first quadrant. Area A is bounded by y=c, x=0, and the curve. Area B is bounded above by the curve and below by y=c. Find c such that (area of A)=(area of B)." I can do this using integrals, but I don't want to solve any cubics. There must be an easier way to find c.

Area Between Curves [01/11/1997]
Find the area bounded on the right by x+y = 2, on the left by y = x^2, and below by the x-axis.

Area between two Curves [12/24/1995]
Find the area between the curve x = 1-y^2 and the y-axis?

How do I calculate the area and circumference of a given ellipse?

Area of a Curved Figure [07/26/1997]
How can you find the area of a curved figure without using calculus?

Area of an Ellipse [08/03/2001]
Show that the area enclosed by the ellipse x^2/a^2 + y^2/b^2 = 1 is pi*a*b, where a is the longer horizontal part and b is the shorter vertical part of an ellipse.

Area of a Parabola [09/05/1997]
How do you find the area of a parabola? (I just finished Algebra 2.)

Area of a volume of revolution [11/22/1994]
I am a little confused about finding volumes when graphs are revolved around an axis - specifically about finding the volume of a disk and the volume of a washer.

Area of Union of Two Circles [6/10/1996]
If the effective length of a rope tied to a goat is L, and the goat can eat exactly half of the grass in a field, express L in terms of R.

Why is the area under the parabola y = x^2 between the y-axis and the line x = b equal to b^3/3?

Average Radial Distance of Points within a Circle [03/26/2003]
I'm trying to determine the average value of a circular/radial gradient that is at full value (white, call it 100% brightness) in the center, and drops in a linear fashion to zero (black, call it 0% brightness) at the radius.

Average Rate of Change [10/30/2002]
Find the average rate of change of y with respect to x on the interval [2, 3], where y = x^3 + 2.

Balance Point between Converging and Diverging Infinite Series [03/20/2002]
