Mathematics for Chemistry
https://www.maplesoft.com/applications/view.aspx?SID=154267&ref=Feed
This interactive electronic textbook in the form of Maple worksheets comprises two parts.
<BR><BR>
Part I, mathematics for chemistry, is supposed to cover all mathematics that an instructor of chemistry might hope and expect that his students would learn, understand and be able to apply as a result of sufficient courses typically, but not exclusively, presented in departments of mathematics. Its nine chapters include (0) a summary and illustration of useful Maple commands, (1) arithmetic, algebra and elementary functions, (2) plotting, descriptive geometry, trigonometry, series, complex functions, (3) differential calculus of one variable, (4) integral calculus of one variable, (5) multivariate calculus, (6) linear algebra including matrix, vector, eigenvector, vector calculus, tensor, spreadsheet, (7) differential and integral equations, and (8) probability, distribution, treatment of laboratory data, linear and non-linear regression and optimization.
<BR><BR>
Part II presents mathematical topics typically taught within chemistry courses, including (9) chemical equilibrium, (10) group theory, (11) graph theory, (12a) introduction to quantum mechanics and quantum chemistry, (14) applications of Fourier transforms in chemistry including electron diffraction, x-ray diffraction, microwave spectra, infrared and Raman spectra and nuclear-magnetic-resonance spectra, and (18) dielectric and magnetic properties of chemical matter.

Other chapters are in preparation and will be released in due course.

We present an algorithm for unconstrained optimization of experimental data in chemical kinetics using as method a sequential simplex of variable size. An animated plot of progress of a triangular simplex descending across a surface of to converge to an absolute minimum illustrates an implementation of this approach.<img src="https://www.maplesoft.com/view.aspx?si=4289//applications/images/app_image_blank_lg.jpg" alt="Optimization with sequential simplex of variable size" style="max-width: 25%;" align="left"/>We present an algorithm for unconstrained optimization of experimental data in chemical kinetics using as method a sequential simplex of variable size.

https://www.maplesoft.com/applications/view.aspx?SID=4240&ref=Feed
The lagrangian formulation of mechanics has great advantages in practical use. Calculations of this type require finding the derivative of a function with respect to another function. Although our method is a pedagogic approach that might involve longer steps, it is a straightforward attack on this problem, and practically all problems in classical mechanics can be solved once the lagrangian is found. In most real physics problems, there are no analytic solutions to differential equations. We particularly emphasize forming plots numerically. We introduce an example in general relativity, to find the trajectory of a particle near a black hole, which corresponds to the shortest path between two points in a curved space.<img src="https://www.maplesoft.com/view.aspx?si=4240//applications/images/app_image_blank_lg.jpg" alt="Trajectory Near a Black Hole: an application of Lagrangian mechanics " style="max-width: 25%;" align="left"/>The lagrangian formulation of mechanics has great advantages in practical use.

Calculus of variations involves finding a derivative of a function with respect to a function, which Maple does not directly support. With simple substitution, we can, however, solve easily a problem of this type without invoking an external library. We use a problem in classical mechanics to illustrate a procedure to solve the Euler-Lagrange equation, which is the most important application of calculus of variations.<img src="https://www.maplesoft.com/view.aspx?si=4161//applications/images/app_image_blank_lg.jpg" alt="Motion of a Heavy Symmetric Top" style="max-width: 25%;" align="left"/>Calculus of variations involves finding a derivative of a function with respect to a function, which Maple does not directly support.

https://www.maplesoft.com/applications/view.aspx?SID=3856&ref=Feed
The integrated intensity of each band in a system corresponding to transitions between two electronic states of a diatomic molecule is proportional to the square of a matrix element that one can form according to wave mechanics by integration of electronic and vibrational wave functions over electronic and nuclear coordinates. This matrix element can be taken to be a product of a factor involving electronic wave functions and a factor that is the square of an integral of wave functions of vibrational states; this squared integral is called a Franck-Condon factor, and this worksheet enables estimation of this quantity using vibrational wave functions of either an harmonic oscillator or a Morse oscillator.
