Critical point question
having problems finding critical points for this two equation to fined the maximum,minimum or saddle points.
need help to find the critical points for this two equations,really hope someone can help me. really appreciate all your help & support.
How far have you come in your attempts? Where do critical points for a given function occur?
thank you for replying.
im stuck here, unable to find the critical point
x=1 & -1
critical point, = (1,1) & (-1,1) ..is this right???
realyl hope someone can help, appreciate all help & support.
a: Remember that the two derivatives form a system of equations:
or (see why?)
What values for critical points does this give you?
b: Seems right to me, so far, however, you are being a little hasty. It's quite right that
but it also implies that
. See what you missed?
thank you for replying,
x= -1,0 & 1
critical points=(-1,-1)(0,0) & (1,1)
b)you are right, but is my final answer for critical point correct?
critical point=(1,1) & (-1,1) .. i think it has to be correct..not sure,a bit confused though
is this correct?
thank you again for all help & support.
