If the object is displaced a distance a units from it`s equilibrium position and released from rest, the subsequent motion of the object is described by the initial value problem d^2X/dY^2=-w^2X; X(0)=a; dX/dT(0)=0; Where w is a position constant. Solve this initial value problem to find the displacement, X(T), of the object from equilibrium at time T. That`s all. Thank you for your help in advance. Yours, Calvina.

When a differential equation of order n has the form it is called an implicit differential equation whereas the form is called an explicit differential equation. A differential equation not depending on x is called autonomous General application An important special case is when the equations do not involve x . These differential equations may be represented as vector fields . This type of differential equations has the property that space can be divided into equivalence classes based on whether two points lie on the same solution curve . Since the laws of physics are believed not to change with time, the physical world is governed by such differential equations. (See also

12. Interactive Learning In Calculus And Differential Equations With Applications A classroom learning environment based on Mathematics notebooks. http://www.ma.iup.edu/projects/CalcDEMma/Summary.html

Interactive Learning in Calculus and Differential Equations with Applications Click on this picture for a description of how it was generated. The Mathematics Department at Indiana University of Pennsylvania (IUP) established a computerized learning environment, consisting of a classroom with 31 Macintosh Centris 650s and a laboratory with 12 Macintosh LCs, all equipped with Mathematica . Mathematica's notebook feature enables science students to actively learn calculus and differential equations with guided discovery and exploration. The project was funded through a National Science Foundation Instrumentation and Laboratory Improvement grant, number DUE-9351896. IUP's project has several significant attributes. The Mathematics Department is fully implementing this curriculum in all sections of its science calculus sequence and in the two-semester differential equations sequence. Eleven faculty, comprising approximately one third of IUP's mathematics faculty, are coinvestigators. The curricular revisions are being coordinated with the science departments at IUP, who are also integrating active learning and technology in their courses. This collaboration, based on common pedagogical goals and software, will bring more scientific applications into mathematics courses and strengthen the use of mathematics in science courses. All students in the Mathematics Department are involved. Mathematics and Applied Mathematics majors are required to take Differential Equations, and Mathematics Education majors have a unit devoted to the project in the teacher preparation course, Computers and Calculators in Secondary Mathematics.

15. DIFFERENTIAL EQUATIONS AND OSCILLATIONS Many problems in physics are described by differential equations. As a complete discussion of differential equations is beyond the scope of this chapter we will deal only with linear first and second order ordinary differential equations. http://www.physics.orst.edu/~rubin/nacphy/ComPhys/DIFFEQ/mydif2/

DIFFERENTIAL EQUATIONS AND OSCILLATIONS The differential nature of these physical laws in turn may be a reflection of our use of continuous variables like position and probability. (The use of differential equations may also reflect traditionally-trained physicists viewing problems in differential forms). As a complete discussion of differential equations is beyond the scope of this chapter we will deal only with linear first and second order ordinary differential equations. We start with deriving two methods to solve first order differential equations numerically ( Euler and Runge-Kutta ). These methods can be extended to solve second order differential equations which we will do using the harmonic oscillator and the realistic pendulum as examples.
