Step 1
For f(z) = 7 - 7z, we have: To find the zeros, we set f(z) = 0: 7 - 7z = 0 z = 1 So, there is one zero at z = 1. Since this is a polynomial function, there are no poles. Now, for f(z) = 6z^2 - 5z + 4, we have: To find the zeros, we set f(z) = 0: 6z^2 - 5z + Show more…

10. Evaluate the given integral by converting to polar coordinates. Be sure to draw the region of integration in each part. (a) ∬_R (x+y) dA, where R is the region that lies to the left of the y-axis between the circles x^2+y^2 = 1 and x^2 + y^2 = 4. (b) ∬_R ye^x dA, where R is the region in the first quadrant enclosed by the circle x^2 + y^2 = 25.

5. (10 points) Let D be the shaded region below (the area inside the circle of radius 1 centered at (1,0), and outside the circle of radius 1/2 centered at (1/2,0)). (a) (5 points) Express ∬_D f(x,y) dA as the sum of three double integrals in Cartesian coordinates, each in the order dy dx. (b) (5 points) Express ∬_D √(x^2 + y^2) dA in polar coordinates. Do not evaluate the integral.
