I think there is a typo in the question.
There is no typo in the question, I'll try to rewrite to so that it is hopefully easier to understand basically it's e power of x minus e power of negative x over e power of x plus e power of negative x y=((e^x)(e^x))/((e^x)+(e^x)) hope this helps
if y = ((e^x)(e^x))/((e^x)+(e^x)), it is not true that y = 1  y^2. Consider the case when x = 0. In that case y = 0.
this is differentiation trying to prove that when y is differentiated, dy/dx=1y^2. Are you saying that this is not achievable?
So there was a typo, because you didn't include dy/dx before
ok, that was my bad , should have made it clearer, are you able to help with my quesrion now?
