Light, Chroma & Lamp Engineering Applications
https://www.maplesoft.com/applications/view.aspx?SID=154656&ref=Feed
Emulation of the spectral distributions of many non-LED popular lamps, allows for direct utility calculations based on many different parameters including chromaticity, space type, lifetime, occasion, application, cost and efficiency. 7 such parameters are used with constrained weight optimization to fish out some of the more popular lamp types used in many situations today. Will be modified some time later to deal with LEDs. Based on elemental spectral data published by NIST.<img src="https://www.maplesoft.com/view.aspx?si=154656/L14(1).jpg" alt="Light, Chroma & Lamp Engineering Applications" style="max-width: 25%;" align="left"/>Emulation of the spectral distributions of many non-LED popular lamps, allows for direct utility calculations based on many different parameters including chromaticity, space type, lifetime, occasion, application, cost and efficiency. 7 such parameters are used with constrained weight optimization to fish out some of the more popular lamp types used in many situations today.

This problem solves for the minimal radius of curvature for designing and building a banked curve on a road assuming a constant speed and elevation.

It is written using the modern mechanics introductory physics approach of Chabay and Sherwood and demonstrates the pedagogical value of Maple's ability to teach physics and to solve problems starting from fundamental principles, i.e., a top-down approach. This is in contrast to most computational systems where one codes starting from a specific example before implementing the fundamental principles.<img src="https://www.maplesoft.com/view.aspx?si=154648/Banked_Curve_Image.jpg" alt="Minimal Road Radius - From a physics educator's perspective" style="max-width: 25%;" align="left"/>This problem solves for the minimal radius of curvature for designing and building a banked curve on a road assuming a constant speed and elevation.

You're driving a car on an incline, but the brakes lock up. How far will your car skid?
<BR><BR>
This application uses Newton's 2nd law and laws of motion to derive an equation that gives the distance your car will skid (also known as the braking distance). This equation shows that the braking distance is proportional to the square of the velocity at the start of the skid.<img src="https://www.maplesoft.com/view.aspx?si=154632/Braking_Distance_of_a_Skidding_Car.png" alt="Braking Distance of a Skidding Car" style="max-width: 25%;" align="left"/>You're driving a car on an incline, but the brakes lock up.

https://www.maplesoft.com/applications/view.aspx?SID=154598&ref=Feed
The following is a detailed study of the motion of an unconventional Atwood Machine where one mass is constrained to move along a fixed vertical axis.
The differences with the regular Atwood Machine are :
1- the tension T on the string on either side of the pulley though it is the same, however it is not constant in the present case because of the obliquity of the 2d part of the string.
2- the unique and constant acceleration (a) in the simple machine is replaced in here with two different and variable accelerations whose ratio is however constant.
3- In the simple machine the constant acceleration makes plotting and animation of the system a straightforward procedure according to
s = (1/2)*at^2.However in the modified Atwood machine that we present in here the accelerations being variable there is no way to get the displacement as a direct function of time. This seems to make plotting & animation an impossible task. However we were able to devise a trick to overcome this difficulty.<img src="https://www.maplesoft.com/view.aspx?si=154598/Modified_Atwood_Machine.jpg" alt="Atwood Machine" style="max-width: 25%;" align="left"/>The following is a detailed study of the motion of an unconventional Atwood Machine where one mass is constrained to move along a fixed vertical axis.

This application solves a set of compatible equations of two or three variables. For two variables, it also graphs the intersection point of the variable "x" and "y". If we want to observe the intersection point closer we will use the zoom button that is activated when manipulating the graph. If we want to change the variable ("x" and "y") we enter the code of the button that solves and graphs. For three variables, the intersecting planes are shown.

So, this was introduced into my son's high school Precalculus I class, and he really didn't understand it. After reading his textbook, I could understand why, the explanation was terrible. So, I decided to do a few examples for him, to show him how it would work. While I used Maple to do the computational pieces, I didn't use any built-in functions, I kept it as simple as possible.<img src="https://www.maplesoft.com/view.aspx?si=154517/b0e3e02e0b878253dcb11a11a2b75fce.gif" alt="Linear Optimization Examples" style="max-width: 25%;" align="left"/>So, this was introduced into my son's high school Precalculus I class, and he really didn't understand it.

This problem models a thundercloud by a +40C charge at 10km height, -40C charge at 5km height and a 10C charge at a 2km height. It then has an airplane flying at 8km through the cloud. The crux of the problem is to calculate the Electric field on the plane beginning at the left of the cloud through to the right of the coud.
I placed the y axis along the charges within the cloud. his means the airplane has a fixed y value and just changes in x. I also numbered the charges from bottom to the top.<img src="https://www.maplesoft.com/view.aspx?si=154519/b9715d1a184de2946329d1d396866539.gif" alt="Plane flying through a thundercloud, calculating the E field" style="max-width: 25%;" align="left"/>This problem models a thundercloud by a +40C charge at 10km height, -40C charge at 5km height and a 10C charge at a 2km height.

https://www.maplesoft.com/applications/view.aspx?SID=1753&ref=Feed
The algebraic technique of partial fraction decomposition typically appears first in the integral calculus course as part of the methodology of integrating rational functions; and second, in any course such as differential equations where Laplace transforms must be inverted. If the Laplace transform is used in an engineering course, partial fraction decompositions must generally be implemented over the complex field so that all factors are linear.
This column describes how to obtain the partial fraction decomposition in Maple, either with irreducible quadratic factors or with strictly linear factors. We also suggest some pedagogic devices for providing insight into the algebraic processes involved.<img src="https://www.maplesoft.com/view.aspx?si=1753/partialfrac.PNG" alt="Classroom Tips and Techniques: The Partial Fraction Decomposition" style="max-width: 25%;" align="left"/>The algebraic technique of partial fraction decomposition typically appears first in the integral calculus course as part of the methodology of integrating rational functions; and second, in any course such as differential equations where Laplace transforms must be inverted.

Some boundary value problems for partial differential equations are amenable to analytic techniques. For example, the constant-coefficient, second-order linear equations called the heat, wave, and potential equations are solved with some type of Fourier series representation obtained from the Sturm-Liouville eigenvalue problem that arises upon separating variables. The role of Maple in the solution of such boundary value problems is examined. Efficient techniques for separating variables, and a way to guide Maple through the solution of the resulting Sturm-Liouville eigenvalue problems are shown.<img src="https://www.maplesoft.com/view.aspx?si=4971/R-23EigenvalueProblemsforODEs.jpg" alt="Classroom Tips and Techniques: Eigenvalue Problems for ODEs" style="max-width: 25%;" align="left"/>Some boundary value problems for partial differential equations are amenable to analytic techniques.
