Also, (don't know if it's a mistake on my part) but the values of A and B aren't coming out like the ones above after substitution. submitted by /u/CuriousForeverium [visit reddit] [comments ..read more

I’m cooked for my final can y’all help me… I need to have these equations for the Fourier series for the heat and wave equation, but I’m struggling hella with computing the Separation of variables necessary to get the red equations, if anyone can link or help with some resources it would be a blessing. I need the equations for mixed dirichlet and Neumann BC,s also I’m a bit confused on how one actually solves for the Bn coefficient so any insight would also be appreciated! submitted by /u/Creative_Commons2 [visit reddit] [comments ..read more

Sea el campo ~P (x, y, z) = (y, x, 2). Verifica el teorema de la divergencia (o ley de Gauss) para los flujos considerando el volumen encerrado por las superficies x2 + y2 + z2 = 4; z = −1. submitted by /u/No_Card603 [visit reddit] [comments ..read more

I'm trying to calculate the range of a frisbee for a physics project and got stuck while trying to solve for velocity as a function of time. I'm pretty sure it's just unsolvable but I wanted to check with people of more expertise (I only really got into this in the past week or so). The only variables are Vx and Vy. https://preview.redd.it/7xhcnyw1202d1.png?width=1932&format=png&auto=webp&s=bc935ee019bd64a32528320ded508df2db60e0ed submitted by /u/tragic_chees3 [visit reddit] [comments ..read more
