Caitlyn pose la question :
I know how to take an antiderivative. But this one's stumping me. I need it to finish a problem.

Indrajit pose la question :
∫4e^x + 6e^-x/(9e^x + 4e^-x)dx = Ax + Bloge(9e2x - 4) + C
then A=?......B=?.....C=?
plz solve it...."^" stands for "to the power of"....

Antiderivative of 1/(x(1 - x)) |
2008-10-22 |
|
Matt pose la question :
derivative of dx/(x(1-x))
From what I've seen I should break apart the equation as such
derivative of dx/x - dx/(1-x)
and then get the 2 corresponding log functions.
If that is correct why does this factoring work, if that is incorrect what is the proper way to find the derivative.

f(x+y) = f(x) + f(y) + 2xy |
2007-11-01 |
|
Marcia pose la question :
For all real numbers x and y, let f be a function such that f(x+y) = f(x) + f(y) + 2xy and such that the limit as h -> 0 of f(h) / h = 7, find: f(0), use the definition of the derivative to find f'(x), and find f(x).

Velocity and acceleration |
2005-10-27 |
|
Candace pose la question :
When taking the integral of the position function, you get the velocity function, and the same for velocity to acceleration. So when you do each of these, you get a function. But when you integrate on a graph, you get an area under a curve. The area is un units squared- where do the units go when you make it an equation? How can a function be an area?

The tide at a boat dock |
2005-01-11 |
|
Abraham pose la question :
The tide at a boat dock can be modeled by the equation
y = -2cos(pi/6 t) + 8,
where t is the number of hours past noon and y is the height of the tide, in feet. For how many hours between t=0 and t=12 is the tide at least 7 feet?
