I'm having problems using the quotient rule and am hoping that someone can help.
g(t) = A / 1+ BE^-t
Using the quotient rule the numerator simplifies to
0 - A(-BE^-t) = ABE^-t
I don't see how (1 + BE^-t)(A') simplifies to 0,
and how -A(1 + BE^-t)' simplifies to -A(-BE^-t).
In the latter if e is raised to the -t shouldn't that come down using the power rule and then it's e ^t-1?
Will someone please help?
