Hello, I am wondering where my or Mathematica's error in reasoning lies: In[1]:= Integrate[g[z], {x, 0, a}] Out[1]= a*g[z] ok, because the function g does not depend on x. In[2]:= Integrate[g[z], {z, 0, c}] Out[2]= Integrate[g[z], {z, 0, c}] ok, function g is not specified at the moment. In[3]:= Integrate[g[z], {z, 0, c}, {x, 0, a}] Out[3]= Integrate[a*g[z], {z, 0, c}] also ok. Now with the integration order reversed: In[4]:= Integrate[g[z], {x, 0, a}, {z, 0, c}] Out[4]= a*g[z] ?? why this result ??
