May 20, 2013 · Equal refers to semantic equality whereas SameQ is syntactic equality. For instance, Sin[x]^2+Cos[x]^2 and 1 are the same number, so they are equal semantically.

Sep 22, 2012 · The way to "define" a function without specifying an expression is to not define it. Just use it. Example: D[f[x] g[x],x] (* ==> g[x] f'[x] + f[x] g'[x] *)

Oct 12, 2011 · Case q = 0: This is a special case that Mathematica misses in the general result, as it implies a constant integrand. (I'll often miss it, also, when doing this by hand, so …

Mar 19, 2012 · That means Mathematica doesn't know how to caculate a symbolic result. It's just the first root of the polynomial. But it does know what is its numerical value: In[7]:= N@Root[-1 …

Sep 17, 2012 · I was wondering if there was any way to have mathematica find the solution to Schrodinger's equation [(−h^2/2m)(d^2ψ/dx^2) + kx^2ψ=Eψ] for a particle centered at the …

Apr 6, 2011 · I am wondering if you have good ways to show plots inside a loop in mma. Usually, the output of Plot function is not shown, for example in the following code: For[i = 1, i <= 10, …
