It also gives shear and moment piecewise functions with evaluations at the upper and lower bounds of the functions. Please read the attached document before using. *Update 1: Now able to reattempt section entries. *Update 2: Now evaluates maximum values and cleans up variables after running.
This application can solve the Bernoulli Energy Equation using compressible or incompressible flows for unknown variables.

Given any date, local time and time zone including daylight saving the program finds for binary star systems, the orbital elements of which are known, the position angle of the companion B referred to primary object A ( assumed to be fixed ) and the separation in arcsec. The data of twenty systems are already stored on page 1.3 of the file. Documentation on page 1.1 including an illustrating figure on page 1.4 .

This program calculates the forces, cable length and/or the maximum sag of a cable or rope that is fixed in two points A (xa,ya) and B (xb,yb) and is subject to a uniformly distributed load q. The supports may be on the same horizontal level ( ya=yb=0 ) or may have different heights ( ya=0, yb<0 or yb>0 ). The results depend on the inputs you have carried out.
This program determines for a cable or rope being subject to its dead load q the internal force F,res, its horizontal and vertical components ( F,hor , F,vert ) as well as the sag of the cable.

This library contains just about every mathematical equation used over Chemistry I and Chemistry II. Additionally, I also put in some equations I derived as shortcuts, like stoichiometric relationships solved for 1. Be aware that representation of some variables may be different due to nSpire limitations (e.g. concentrations like [X] will be rendered as X_c). Programs like mass("CH3COOH") were included from previous author Nelson Sousa's work. If you wanted to, you could copy and paste the periodic table app by Nick Steen in here, too: http://www.ticalc.org/archives/files/fileinfo/444/44465.html
Balance chemical reactions and compute masses of compounds. Examples: mass("H2SO4"), balance("H2+O2=H2O"). Formula syntax supports standard organic chemistry notation (like CH3COOH or CH3CH2CH2CH3) and parenthesis (like K4Fe(CN)6). Also includes functions to determine names, symbols and atomic numbers of elements.
