Math 237 Assignment 3 Due: Friday, Jan 28th * 1. Find the first and second partial derivatives of a) f ( x, y ) = | 2 x 2 - y | . b) g ( x, y ) = xe x +cos y . * 2. Let f ( x, y ) = xy x 2 + y 2 . a) Find the equation of the tangent plane of f at (2 , 1 , 2 / 5). b) Approximate f (1 . 9 , 1 . 1). * 3. Let f ( x, y ) = ( x 4 y 2 x 2 + y 2 + 1 if ( x, y ) 6 = (0 , 0) 1 if ( x, y ) = (0 , 0) . a) Determine f x (0 , 0) and f y (0 , 0). b) Determine f x ( x, y ) for all ( x, y ) 6 = (0 , 0). c) Determine if f x is continuous at (0 , 0). 4. Find f x (0 , 0) and f y (0 , 0) for f ( x, y ) = ( x 3 - y 3 x 2 + y 2 + 1 if ( x, y ) 6 = (0 , 0) 1 if ( x, y ) = (0 , 0) . 5.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
