PAGE 1 - CRITICAL THINKING PORTION

Create directory named myDirectory.

Create second directory inside myDirectory named Test.

Finally, create file inside the Test directory named file1.

Change the permissions associated with myDirectory to read only.

Once you have done this, see if you can write to file1.

Find the area of the following surface using the given explicit description of the surface The paraboloid z = 5 (x2 +y?), for 0sz s 180 Set up the surface integral for the given function over the given surface S as a double integral over a region R in the xy-plane S R (Type an exact answer, using it as needed.)Calc 2 - Math 166 3. (14 points) An aquarium is in the form of a lower hemisphere with radius r = 5 inches. What is the surface area of the aquarium? (Hint: Consider a lower hemisphere as being generated by rotating a lower quarter-circle around the y-axis.)(1 point) Chen F = xi + 2(x - y)j + 2(x + y) k. (1) Compute the fundamental cross product F, x Fy = (81)+(2x-2y)j+(-2y-2xjk (2) The norm of the fundamental cross product F, x F = sqr1(8x*2 +By*2+64) (3) Find the surface area given parametrically by F for * + y's 9 Surface Area =Compute the volume of the solid which lies under the surface z = 1 y2 and above the surface z = $2. (Note: the rst thing you will need to do is figure the region R over which you will need to integrate. When evaluating the integral you may need to review some of the trig substitution / trig integrals stuff from Calc II)
