Differentiating a logarithmic function in exercise, find the derivative of the function. see examples 1, 2, 3, and 4.
f(x) = ln {1 + e^x/ 1 - e^x}

Where’s the stuff st? ? lol sorry

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
