Why I Needed Maple to Make Cream Cheese Frosting
http://www.maplesoft.com/applications/view.aspx?SID=125069&ref=Feed
<p>A recipe for cream cheese frosting I was making called for 8 oz. (about 240 grams) of cream cheese. Unfortunately, I didn't have a kitchen scale, and the product I bought came in a 400 gram tub in the shape of a<strong> truncated cone</strong>, which has a rather cumbersome volume formula. <br />Given the geometry of this tub, how deep into the tub should I scoop to get 240 grams? The mathematics is trickier than you might think but lots of fun! And the final, tasty result is worth the effort!</p><img src="/view.aspx?si=125069/philly_thumb.png" alt="Why I Needed Maple to Make Cream Cheese Frosting" align="left"/><p>A recipe for cream cheese frosting I was making called for 8 oz.

http://www.maplesoft.com/applications/view.aspx?SID=100509&ref=Feed
<p>The idea of writing this article came to me on the 25th of June 2003 when I was listening to Cairo radio announcing that Maghrib prayer is due in Cairo city while I was sitting in my home town at 400 miles North East of Cairo. What is interesting is that at exactly the same time a next door mosque, in my home town, was also calling for the Maghrib prayer. This makes me wonder : how could it be that sunset is simultaneous at two locations separated by a distance of 400 miles from each other and at different Latitudes & Longitudes. As a reminder Maghrib prayer time occurs everywhere at sunset. <br />In what follows we explore this issue and try to prove or disprove the simultaneity of sunset at two different locations. In so doing we are led to some interesting conclusions and as a bonus we got ourselves an animation of the Terminator circle on the surface of the globe. <br />Aside from its modest value and its originality ( I am not aware of anything similar to it ) this article is a good exercise in Maple programming. <br />May this article be a stimulus for some readers to get interested in Astronomy which is a science as ancient as the early human civilizations. <br /><br /></p><img src="/view.aspx?si=100509/thumb.jpg" alt="Terminator circle with animation" align="left"/><p>The idea of writing this article came to me on the 25th of June 2003 when I was listening to Cairo radio announcing that Maghrib prayer is due in Cairo city while I was sitting in my home town at 400 miles North East of Cairo.

<p>It is a well known fact that sines & cosines of some angles can be expressed in square root radicals.<br />This is the case of sines & cosines of the following angles in degrees : <br />30, 45, 60, 72, 30/2 = 15, 72/2 = 36, 36/2 = 18, 30+18 = 48, 48/2 = 12, 12/2 = 6, 6/2 = 3, 3/2 = 1.5, <br />and all multiples of 3 degrees by a power of 2 are expressible in square root radicals only. <br />This is related to the fact that these radicals can be get from the double of the angle formulas which involve square root radicals only.<br />It is a remarkable fact that all angles counted in degrees as powers of 2 → <br /> n<br /> 2 <br /> such as:<br /> 2deg, 4deg, 8deg, 16deg, 32deg, 64deg, ... , etc.<br />have their sines & cosines which can not be expressed as pure square root radicals but as a combination of cubic & square root radicals.<br />The same holds true for all angles counted in degrees as multiples of 5deg by a power of 2 → <br /> n<br /> 5.2 <br /> such as:<br /> 5deg, 10deg, 20deg, 40deg, 80deg, ... , etc.<br />The purpose of this article is double:<br /><br />1st Purpose - To show how to solve a famous 16 century challenging problem, involving many levels of square root radicals, using Maple powerful calculating engine.<br /> <br />2d Purpose - To find a way to express cosine & sine of any angle from 1 degree on in a combination of cubic & square root radicals.

Properties of the inverse trig and hyperbolic functions in Maple depend on Maple's choices of branch cuts and principal branches. Some of this information is available to the user, and some can be deduced. In this month's article, we show how to determine principal branches and branch cuts for these twelve functions, and then provide a tool for assembling the information in a user-friendly graphical format.<img src="/view.aspx?si=6932/Untitled-1.jpg" alt="Classroom Tips and Techniques: Branches and Branch Cuts for the Inverse Trig and Hyperbolic Functions" align="left"/>Properties of the inverse trig and hyperbolic functions in Maple depend on Maple's choices of branch cuts and principal branches.

Stemming from a user's query, we explore how to generate a stepwise solution of a trig equation. Originally, the user wanted to know if the complete solution could be developed in the "Equation Manipulator" but we show that only part of the solution can be obtained this way. A complete solution requires use of a number of Maple's syntax-free features, including palettes, the Context Menu, and the "Equation Manipulator."<img src="/view.aspx?si=5680/Stepwise_Solution_of_a_Trig.gif" alt="Classroom Tips and Techniques: Stepwise Solution of a Trig Equation" align="left"/>Stemming from a user's query, we explore how to generate a stepwise solution of a trig equation.

http://www.maplesoft.com/applications/view.aspx?SID=1411&ref=Feed
This is a set of 11 Maple lessons for high school Trigonometry, developed by Gregory Moore of Orange Coast College. The lessons can also supplement a course in Precalculus or Calculus.
They are designed so you can present each topic as you would during a normal lecture but using Maple as the main presentation tool. The students do not have to understand Maple syntax to benefit from the lessons.
With these Maple lessons, you can carry a topic far beyond what is possible on the blackboard. You can generate a new example or diagram instantly just by changing a few values in the worksheet.
You can show more interesting examples than you could on the board, where the examples always had to be planned to work out "nice". Maple computes the dirty work, so the class can focus on the thinking steps.<img src="/view.aspx?si=1411/trig_logo.gif" alt="Trigonometry: Complete Set of Lessons" align="left"/>This is a set of 11 Maple lessons for high school Trigonometry, developed by Gregory Moore of Orange Coast College.

http://www.maplesoft.com/applications/view.aspx?SID=4739&ref=Feed
This package of Maple classroom modules by Gregory A. Moore of Cerritos College is designed to enliven the teaching of mathematics curricula at the high school, community college and beginning university levels. Each of the 49 worksheets, categorized in 13 self-contained modules, supplements a particular lecture topic. The modules cover the full spectrum of topics required for a ground level competence in mathematics.
Supplementing your lectures with these interactive worksheets will open portals to mathematical learning and insight that are simply not possible with chalk alone. They empower the student to experience the beauty of mathematics with less of the drudgery and fear that accompany pure paper and pencil approaches. All concepts are illustrated both algebraically and with interactive color graphics and animations. Each worksheet is ready to use but can also be easily customized by the instructor.
Mr. Moore's essay "Integrating Maple into the Math Curriculum - A Sensible Guide for Educators" (Linked below as Worksheet Output), will guide you through the incorporation of these Maple modules into your classroom instruction.<img src="/view.aspx?si=4739/post_math.gif" alt="Post-Secondary Mathematics Education Pack: Complete Set of Lessons" align="left"/>This package of Maple classroom modules by Gregory A.
