Chemistry App for the TiNspire CX CAS at has been updated : Bases, Acids, Equilibrium, Dissociation Constant, Valence Electrons

Sunday, December 18th, 2016

It seems that the Stoichiometry section of our Step by Step Chemistry App has doubled over the last few months, lots of new computational Chemistry has been added. Find app updates below:

– Valence Electrons of Atoms and Molecules
– Equilibrium Constant Kc
– Equilibrium Composition
– Kp = Kc*(RT)^n
– Equilibrium of weak bases
– Equilibrium of weak acids
-%-Dissociation and Dissociation Constant K ,
– Find pOH and PH of Bases.
– Improved Gas Laws
– Improved Step by Step Equation Balancer
– Mole <-> Mass Converters
– Rydberg Formulas

Calculus Made Easy App for the TiNspire CX CAS at has been updated : Newton law of Cooling, Parametric Eqns, Root Test , etc

Sunday, December 18th, 2016

We love Calculus and enjoyed implementing the following updates:

– Differential Equations: Eulers Method, Newton Law of Cooling, Radioactive decay -Parametric Equations : given Velocity v(t) find Tangentline, Curve Length, etc – Convergence Test: The Root Test was added
– Further improvements to Step by Step L’hopital Rule, Limits and Step by Step Integration were made
