1. The problem statement, all variables and given/known data Hi all , again i got stuck onto this iffy bit , question is: find dy/dx of the curve and hence its coordinates of the statinonary point. y= 4 - 2/(2x-1)^2 -x 2. Relevant equations du/dx x dy/du 3. The attempt at a solution well this is how i started off: let u = (2x-1) , y= 4-2(u)^-2 - x du/dx= 2;dy/du:4u^-3-1 2x[4u^(-3)-1] [8u^(-3) -2] to find stationary points i will let dy/dx= 0 and solve the equation ?am i on the right track so far?
