First and second partial derivatives

I previously made the following post: The problem is: Z = X COS Y - Y COS X I am to find all of the first and second partial derivatives of this problem. Will you please solve this problem in detail so that I may use the method you show to solve similar problems? I received the following response: The problem is: Z = X COS Y - Y COS X Solution. As Z = X COS Y - Y COS X, Zx=cosY+YsinX and Zy=-XsinY-cosX So, Zxx=YcosX, Zyy=-XcosY and Zxy=-sinY+sinX Note: Zx and Zy denote the first partial derivatives with respect to X and Y, respectively. Similarly, Zxx, Zyy and... click for more

1. Sergio internet provider charges its customers $7 per month plus 5 cent per minute of on-line usage. Sergio received a bill from the provider covering a 3-month period and was charged a total of $57.00 . How many did he spend on line during that period? Round to the nearest whole minute , if necessary) 2. A certain store has a fax machine available for use by its customers. The store charges $2.15 to send the first page and $ 0.65 for each subsequent page . USE an inequality to find the number of pages that can be faxed for $6.05.
