Hey all
I had a question on my maths paper today, which I had NO idea how to answer.
It was to find the stationary points of:
y = x + 4/(x+1)
So I go ahead and differentiate:
y = x + 4(x+1)^-1
y`= 1 - 4(x+1)^-2
y`= 1 - 4/((x+1)^-2)
And equate it to 0....
1 - 4/((x+1)^-2) = 0
And then I'm stuck! I can't believe I got stuck at something which seems to be trivial algebra. Help would be appreciated - I would like to know how to approach a question like this in future (since I'm sure I should know how to do this!)
Thanks a lot.
