So when i use the following command, I get the following error
DSolve[y'[x] - y[x] == 3, y[x], x]
DSolve::deqn: Equation or list of equations expected instead of False in the first argument False. >>
But when i change the variable y[x] and y'[x] to s[x] and s'[x], It works
why is this?
In[185]:= DSolve[s'[x] - s[x] == 3, s[x], x]
Out[185]= {{s[x] -> -3 + E^x C[1]}}
DSolve[y'[x] - y[x] == 3, y[x], x]
