Exercises on Partial Derivatives

Click For Summary
The discussion focuses on exercises related to partial derivatives, specifically from a resource provided by the University of Alberta. A user requests help in solving the first two problems due to an inability to read the answers. They share their own answers, which include a derivative expression and a simplified fraction. Another participant confirms the user's answers and expresses appreciation for the University of Alberta's resources. The thread highlights the collaborative effort in understanding partial derivatives.

here there are Exercises on Partial Derivatives: http://www.uAlberta.ca/dept/math/gauss/fcm/calculus/multvrbl/basic/partl_drvtvs_exrcss/partl_dervtv_exrcss.htm
can comeone please solve the first two problems (for some reason i can't read the answers).
my answers:
1. 3(3xy-4y^2)^2(3x-8y)
2. y/(x+y)^2

thanks in advance.

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
