Subhayu can you explain 4 ?
For upwards , the 1st derivative must be greater than 0
Which concludes x<1
Now for concave second derivative must be less than 0
Which concludes x>1/2
Iam stuck here
Please help
And for that Euler's theorem I have taken a function (xy)^n and then I have substituted its partial derivatives in the given equation. Am I going right ?
