Multivariable calculus

Evaluate: ∮ 3? 2 ?? + 2???? using two different methods. C is the boundary of the graphs C y = x2 from (3, 9) to (0, 0) followed by the line segment from (0, 0) to (3, 9).

2. Evaluate: ∮(8? − ? 2 ) ?? + [2? − 3? 2 + ?]?? using one method. C is the boundary of the graph of a circle of radius 4 oriented counterclockwise

(MUST BE DONE IN C (NOT C++)) Instead of using two different variables, define a structure with two members; one representing the feet and the other one representing the inches. You will also use three functions; one to initialize a structure, another one to check the validity of its values and one last one to print them out. First, go ahead and define your structure. Next, declare a structure of this type inside main. Then, call your first function (this...

2. Accounting procedures allow a business to evaluate their inventory costs based on two methods: LIFO (last in first out) or FIFO (first in first out). A manufacturer evaluated its finished goods inventory (in $000s) for five products with the LIFO and FIFO methods. To analyze the difference, they computed FIFO − LIFO for each product. We would like to determine if the LIFO method results in a lower cost of inventory than the FIFO method. Product FIFO (F) LIFO...

In an effort to evaluate different methods of teaching a foreign language, a researcher examined the performance of students learning Spanish under four different teaching methods. Group 1 learns in a traditional lecture/lab format; group 2 is taught from a programmed text; group 3 is taught from podcasts; and group 4 is taught from videos of people and life in Spain. After several weeks of instruction, all students were given a Spanish quiz; these scores were recorded: Group 1 Group...
