Some of the geometric formulas we take for granted today were first derived by methods that anticipate some of the methods of calculus. The Greek mathematician Archimedes (ca. 287—212; BCE) was particularly inventive, using polygons inscribed within circles to approximate the area of the circle as the number of sides of the
We can estimate the area of a circle by computing the area of an inscribed regular polygon. Think of the regular polygon as being made up of n triangles. By taking the limit as the vertex angle of these mangles goes to zero, you can obtain the area of the circle. To see this, carry out the following steps:
2. Using the expressions that you obtained in step 1, express the area of the isosceles triangle in terms of

- Question 16arrow_forwardThe figure shows two circles C and D of radius 1 that touch at P. The line T is a common tangent line; C, is the circle that touches C, D, and T; C, is the circle that touches C, D, and C;; C3 is the circle that touches C, D, and C3. This procedure can be continued indefinitely and produces an infinite sequence of circles {C,}. Find an expression for the diameter of C, and thus provide another geometric demonstration of Example 8.

Ship A is sailing east at 20 km/h, while ship B is sailing north at 10 km/hr.arrow_forwardQ.1: The length of rectangular piece of paper exceeds its breadth by 5cm. If a strip of 0.5cm wide be cut all round the piece of paper, the area of the remaining part would be 500 square cms. Find its original dimensions.arrow_forwardDemonstrate your learning by formulating your own real-life problem and its corresponding solution. Create a situation, or story about it. Focus your problem on the topics you have learned from module 5. Create only one problem. Topics are: "illustrating secants, tangents, segments, and sectors of a circle" Just pick one.arrow_forward
- 2) The point P(x, –) lies on the unit circle in quadrant III. Find its x co-ordinate. Page 1 of 5arrow_forwardQuestion 5 Suppose that you want to create a rectangular animal enclosure using 80 linear feet of fencing. You also want to incorporate a pre-existing stone wall running 40 feet in a straight line. |Stone Wall (40 ft) (a) Let x be the length of fencing used on the side containing the wall. Determine the side lengths for the remaining sides of the rectangle in terms of this x, keeping to the constraint that 80 feet of fencing available. you have (b) Determine the objective function A(x) for the area of the enclosure given the value of x. Determine the value of x that maximizes this function's output. (c) Based on the scenario, determine the appropriate restriction to the domain of A(x) and maximize area with respect to that restriction.arrow_forward(part A) What is the objective function F for this problem, before taking any constraints into account? Your answer should be an expression involving both x and y explicitly. F(x,y) =D (part B) What is the constraint equation for this problem? Your answer should be an equation involving both x and y explicitly. answer: (part C) Write the objective function in te ns of x only, the total length of the enclosure. Your answer should be an expression that involves x explicitly but not y. f(x)%3= (part D) The interval of interest for f(x) is. Write your answer using interval notation. (part E) Find the dimensions of the enclosure that requires the least amount of fencing. You answers should be exact numbers. No decimal approximations. y3=arrow_forward
