Consider the critical points of f(x). What is the greatest value of the x-coordinates of the critical points? Give your answer correct to 2 decimal places. f\left(x\right)=f(x)=14x^4-2x^2+5

#### Extending Differentiation (Question)

A curve has equation y=(x2+1)4+2(x2+1)3. Show that dy/dx=4x(x2+1)2 (2x2+5) and hence show that the curve has one stationary (critical) point. State the coordinates of the stationary point and, by...

#### Find the side lengths x and y of the largest area where L is a given length for the diagonal. At the critical point, y=? x=? A=?

It says to eliminate one variable so I eliminated x.
A=xy
L2=x2+y2
x=(L2-y2)1/2
A=y*(L2-y2)1/2
=(L2y2-y4)1/2
Derivative =1/2(L2y2-y4)-1/2 *L22y-4y3
I don't know where to go...
