Need help with differentiationWatch this thread
stationary points is when dy/dx = 0 right
so first i would differentiate the equation
then set dy/dx = 0
u should only get one answer
which is ur stationary point
that x that u found, sub in original equation to get y and there u go!
If value of y is sl lower just below and sl lower just above, it is a max
If both sl higher, then min.
If both in same direction, then inflexion point.
You can work out why - I know you believe in using your brain from the bio Q a few min ago!!
