Question

我正在尝试解决方程并输出推导。我没有解决推导的问题，但是当我尝试输出推导时，它总是带有变量名，例如：

{{w0fromxfun1[x] -> (8.46504 miu^(4/9) qi^(4/9) (-1. x + xf)^(4/9))/
   Ep^(4/9)}}
{{uave[x] -> (0.382926 Ep^(1/4) qi^(3/4))/(
   hf (miu (-1. x + xf))^(1/4))}}

See this link for a better view

我解决推导的代码在这里：

equ5 = uave[x] == ((qi Ep^(1/3))/(
    3.59623 hf (hf miu (xf - x))^(1/3)))^(3/4);
diffequsol2 = PowerExpand[FullSimplify[DSolve[equ5, uave[x], x]]] // N;
waveofthemaxes = 
  FullSimplify[
   1/xf Integrate[w0fromxfun[x], {x, 0, xf}, Assumptions -> trivial]];
equ6 = w0fromxfun1[
    x] == ((4.5788*(hf miu qi/((\[Pi]/4)  hf ) (-x + xf))^(1/3))/Ep^(
     1/3))^(4/3);
diffequsol1 = 
 PowerExpand[FullSimplify[DSolve[equ6, w0fromxfun1[x], x]]] // N

我不希望在派生前面使用变量名称，我尝试Fullsimplify和simplify但不起作用。
