how would you differentiate this equation??
dy/dx + e^(x+y) = 0

calculus 
drwls,
Are you sure you want it differentiated? it looks more like a differential equation that one might want to solve. This can be done by rewriting it as
dy/dx = e^x * e^y
dy/e^y = dx*e^x
e^y dy = e^x dx
Integrate both sides
e^y = e^x + C where c is an abrbitrary constant
This can be rewritten as y(x)
