you practised OCR?

I solved the CIEs P1's long ago so I was short on papers to practice.

omaaaar

Let Dy/Dx =Fx

First Derivate the x+ 4/x^2 wali equation to get F'x
and insert F'x = 0 and calculate the value of x (which is 2)

than double derivate and insert x=2 in it and you will have a value ( 3/2) with is greater than 0
greater than 0 is minimum nature
than add x=2 in the first wali eq ( x + 4/x^2 ) and you will get the minimum gradient.

Thanks for elaboration
