Peace!
I want to know the conditions that must be satisfied by a function
f(x) for any of the following two cases to be true (each case independent from the other);
1- \int^a_{-a} f(x) dx = 2 \int^a_0 f(x) dx
2- \int^a_0 f(x) dx = \int^0_a f(x) dx
They gave me confusion when...
Peace!
I have a problem when attaching pics to my messages. I can't know about the pixel size of my attached file. How can I know it? And how can I reduce it if it is larger than the limit?

PS.
I am not sure if this is the correct place of my post, so please forgive me if it is...
Peace!
I am supposed to find the electric force acting on the right rod due to the rod on the left. each is of length 2a and b > 2a. Each rod carries a charge +Q. I have difficulty in finding the integration, especially its limits.

Hi,
I have been a memeber of this forum for sometime and I was not that acive , :zzz: forgive me. I had lots of work and studies to do.
I am back with many questions and hope to be as active as I should be :!!)
I am happy to see myself here again :biggrin:
A string has two parts: one with a very high mass density (per unit length), and the other with a very low mass density. A wave with amplitude A moves from the dense part toward the light part. What will be the amplitude of the wave which is transmitted to the light part?

Hi,
I have been trying to solve the following differential equations I was stuck with them. I will appreciate any help from you;
1- 3 y' +3x/y =2(xy)^4
I have tried Bernoulli but I could not get a standard form.
2- x' -2 x y = y exp (-3y^2)[x exp(-y^2)+ 3(x exp(-y^2))^2]
I have tried here...
Hi all,
I have the following problem which I have tried to solve for a very long time, very very long time indeed- 2 or more years. I am studying here all by myself and I got no one to help me.
I shall not participate in any talk. I have had enough with it.
this problem is in the Schaum's...
Hi all,
My question is, Does any one here have a mathematica 4.0 or 4.1 on a linux box? (RedHat of Mandrake?)
I am facing a font problem and I thought I might have solutione here.

Hi,
I have the following ODE, which I could not solve,
(7x^3+3x^2y+4y)dx+(4x^3+x+5y)dy=0.
I have tried to use the integration factor technique, but I could not find one.
It can be put in the form:
M dx +N dy=0, where M=7x^3+3x^2y+4y, and N=4x^3+x+5y.
Can you help me? And How can it be done...
Hi
Well, I am doing all the study of physics here by myself. I have The fundamentals of physics book, but all I need is the solutions to its problems. I have tried to search for such solutions but I could not find any, do you think you can help me in finding some of the solutions?

hi, how are you all?
I am new to this forum, and I can't tell you how much delighted I am to be here with you. I can't express my joy and happiness to see this forum. I loved it since the time I saw it- even before reading anything.
Thank you veru much for making my dream come true, to see a...
