Homework Statement Develop a Heapsort algorithm using java Homework Equations The Attempt at a Solution I have been trying to implement HeapSort in java. Unfortunately I am running into errors. I am printing out the index values and they go up then down and the code does not sort properly. Can...

1. Homework Statement ∫∫S xz dS where S is the boundary region enclosed by the cylinder y2 + z2 = 9 and the planes x = 0 and x + y = 5. 2. Relevant equation∫∫Sf(x,y,z)dS = ∫∫Df(r(u,v)) * |ru χ rv|dA 3. The Attempt at a Solution I think I have broken this up into 3 surfaces. The...

Homework Statement integrate e(x2) Homework Equations The Attempt at a Solution e(x2) = (ex)2 substitute (ex) = u so (ex)dx = du therefore ∫e(x2) dx = ∫u du Unfortunately this is not the correct answer Can someone please tell me what I am doing wrong? Thanks

1. I am trying to determine the value of g based on a simple pendulum. I have graphed a scatter plot with the x-axis as L and the y-axis as P. I have 3 different series for different lengths of pendulum. When I try to find a line of best fit I get something like cx^2 + dx + e and this trend...

1. A spherical mirror is used to form an image 5 times as tall as an object, on a screen positioned 5.0m from the mirror. a) Describe the type of mirror required b) Where should the mirror be positioned relative to the object 2. M = (Di)/(Do) & 1/(Di) + 1/(Do) = 1/(F) 3. I have...

Thanks for all your help I am rotating about the y-axis I am multiplying the entire ∏r2 portion by 2 because my equation only finds the area one half of the resultant solid to find r I divided (1/4x2) by 2 to find the radius of my circles. thanks again

1. Find the volume for the solid obtained by rotating the region bounded by the given curves about the specified line. y=(1/4)(x^2), x = 2, y = 0, about the y-axis 2. Use the disk/washer method of integration to find the volume 3. When I try to solve this problem using small...
