f(x,y)=ln(x2y)+y3x2
For finding fx, we have to differentiate f(x,y) with respect to x as follows:
fx=2xyx2y+y3
Now, for finding fxx, differentiate fx with respect to x.
Try in the same way for fyy.

The analysis of tooth shrinkage by
Loring Brace and colleagues at the University of Michigan’s Museum of Anthropology indicates that human tooth size is continuing to decrease and that the evolutionary process has not yet come to a halt. In northern Europeans, for example, tooth size reduction now has a rate of 1% per 1000 years. In about how many years will human teeth be 90% of their present size?
