There many difficulties with partial derivatives and partial integrals. Need practise for this. E.g find d/dz (e^(yz)/cos(xz)), or the integral of 2x-2y over dy.

Problem 1. You can use the formula dz/dx=-dF/dx/dF/dz.

Problem 1. Observe that 1/cos(xz)=sec(xz).

Problem 2. The answer must be the equation of a plane, not a vector.

Problem 3. Green’s theorem says that the work integral of F over a curve C equals the double integral of dg/dx-df/dy over the region R enclosed by C. Please write an equality with two sides, not just the second double integral.

Problem 4. If the Jacobian is negative, take the absolute value of it.

The equation cos(x)=0 has infinitely many solutions because cos(x) is periodic.
You can find the solutions in the interval [0,2*pi] and the rest are translations of these solutions. In particular, cos(x)=0 and x in [0,2*pi], implies x=pi/2 or x=3pi/2. All solutions have the form
x=pi/2+2*pi*k, or x=3pi/2+2*pi*k, where k is any integer number.

Exam 2 on Tuesday 3/10

Dear all,

Exam 2 will take place on Tuesday after the break, 3/10.

It covers all the problems from Exam 1 (see Exam 1 and Solutions at https://udmmath2410w15.wordpress.com/2015/02/11/exam-1-feedback-and-solutions/), the homework assignments between Exam 1 (2/4) and yesterday (2/25), plus one more homework assignment on section 13.8 (Maxima and Minima of Functions of Two Variables), which will be due on the same day as Exam 2. There will be a separate announcement for this homework assignment.

The exam problems will be variations of Exam 1 and homework problems. So, please review these problems again.

If you have any questions, please ask on Monday after the break in class.
