I would also like to know this? I try to use math functions in signature but unsuccessfully.

Re: Fourier transform method problem

I know that I need to find the results of the equation u = u (x,t) of (d^2*u)/(d*t^2) = a^2 * (d^2*u)/(d*x^2) that satisfied next conditions: u (0, t) = 0, u (l, t) = 0 and initial conditions: u (x, 0) = (4h/l^2) * x * (l - x), ut (x, 0) = 0 Then I suppose, need to ask for nontrivial solution of spe...

Re: Fourier transform method problem

Yes, I tried to solve it but failed... Ok, I will write what I got, but seems it was wrong answer.

Fourier transform method problem

Hello, Transverse shift points with the x-axis wire in time t satisfies the equation: (d^2*u)/(d*t^2) = a^2 * (d^2*u)/(d*x^2) where a^2 = T0/p ( T0 is the tension wire, p is the linear density of wires). We need to find a form of wire at time t , if the ends x = 0, x = L are fixed and in the initial...

Re: Math Books

I know that book that I was most impressed by is "Linear Algebra Done Wrong" written by Sergei Treil. It supposed to be a first linear algebra course for mathematically advanced students. Even so I red a lot of books, this caught my eye because a way of understanding algebra on a different...

I have opportunity to browse around his workbooks and textbooks, but it don't have any sense to me! Like he wrote that textbooks to a lower intelligent people and I don't like that kind of underestimation!

Re: Awesome Teacher Quotes

My teacher (that passed away) always mention us that "One good teacher in a lifetime may sometimes change a delinquent into a solid citizen."

And my favorite quote is "I have discovered such wonderful things that I was amazed… Out of nothing I have created a strange new universe."

Re: How can we make math less scary?

People are scared of math as it is some kind of "science fiction". Please don't be! Everything you will need to learn you can accomplished with practice. Persistent people always better pass in life that smart ones. So keep in your mind that you do not have to be smart to learn math, just ...
