| Missing commas in function definition. In[11]:= a[q_, s1_ , s2_] := ((1 - q + s1*(1 + q*s2))/(1 + s2)) In[12]:= D[a[q, s1, s2], s1] Out[12]= (1 + q s2)/(1 + s2) |
| You are missing a comma: ;-) In[4]:= Reduce[{w == Max[(72 - x - 3 y)/4, 0], x == Max[(60 - w - z)/2, 0], y == Max[(48 - z - 2 w)/3, 0], z == Max[(60 - y - x)/2, 0]}, {w, x, y, z}] Out[4]= w == 78/5 && x == 48/5 && y... |
