Thanks for the suggestion guys! Any books that you suggest I should start reading? Would it be best for me to also learn C? Matlab?

Hi everyone, I want to know what disciplines must I study to become an effective numerical modeler? As a numerical modeler, I expect to be able to generate numerical solutions to mathematical problems (via programming) at the same time I want to be able to explain all aspects of my...

Need career guidance! Nuclear Engineering..or?? Hi everyone! I just graduated from an undergraduate degree in physics...and now I'm stumped as to what i should be doing next. I'm thinking of working at a local company for a year then proceed to taking higher degree courses. As of now, I live...

Hi, I'm currently doing experiments on a 99.9% TiO2 source powder. I was wondering if there is anyway to lower the melting point of this solid? If possible, without compromising its purity. I only have access to an electrical furnace that is capable of reaching a maximum of 1200 degC...

Thanks for the tip! Are there any possible way to solve this? Like possibly an out of this world change in variables (ex let u = lnx)? or series substitution?

Hi~ I'm having trouble with solving a certain differential equation. x2y'' + x y'+(k2x2-1)y = 0 I'm tasked to find a solution that satisfies the boundary conditions: y(0)=0 and y(1)=0 I have tried solving this using the characteristic equation, but i arrived at a solution that is...

ooohhh! i seee! thanks very much! :D now i understand :D

Well, the problem gave me a symmetric square wave f(x). f(x) = 1, when |x|<pi/2 and -1, pi/2 < |x|< pi I was able to solve for its Fourier series expansion given by: f(x) = (4/pi) * \Sigma (-1)n cos(2n+1)x / 2n+1 Now...
