Thank you. I had been hesitating to make the purchase as I had wanted to get the apps for TI Voyage 200; but I decided to get the ones for TI-Nspire CAS CX instead, basically because it has more memory available. These apps you sell have the potential to become addictive so I most likely will be back for more! I think I made the right choice. So, needless to say, I am very impressed. Beauty is in the eye of the beholder. Your programs are my drug of choice. I am sure to enjoy them for the remainder of my life. They are one of the few things worth buying besides food and a good pair of boots.
Thank you very much! Chemistry Made easy for NSpire all set and working…..
Great Customer Support!!!!!
I think I’m in love with you guys!!!!!
Just bought Chemistry Made Easy…..
I was so impressed with CME that I bought AME and PME and they are both first-rate.
I’ll be buying more as they appear.
Your apps have made the Nspire a lot more useful to me than it was – in fact, I’m beginning to like it quite a lot.
Congratulations on the hard work, I suspect your nspire apps will be even more successful than the Ti89 apps.
To solve Differentials such as this one:
We use Calculus Made Easy at www.Tinspireapps.com , select Differentials and enter as follows
Problem solved! Works for any Differential problem.
When computing IHP or indicated Horsepower we can use the Physics Made Easy at www.TiNspireApps.com as follows:
Use option Q under the Energy tab
Next enter Bore, RPM, IMEP, Stroke and Cylinders :
Finally , IHP is computed in bottom box:
Solving inequalities using the TiNspire’s Step by Step Equation Solver at www.TiNspireApps.com is straightforward. Go to menu option 5 1:
Next , enter the inequality given :
Scroll down to view the Sign Chart :
Nun koennen Sie Geometrie Aufgaben wie Volumen, Flaechen, Kreise, Kegel, Wuerfel, Quadrate, Kegelstuempfe, Kugeln, Dreiecke und vieles mehr mit der Geometrie Leicht Gemacht App unter https://www.tinspireapps.com/deutsch/?a=GLG loesen: Einfache die geomtrische Figur im Menu aussuchen, die gegebenen Werte eingeben und schon wird die Antwort angezeigt, Ganz leicht zu bedienen, und hilft ungemein in den Geometrie Klassen. Kostenlose Trials.
If we are asked to solve the 1. Order Differential Equation y’+4y=8 we see that it is Linear in y and thus use option B in Differential Equations Made Easy at www.TiNspireApps.com as shown below:
Next enter the coefficients 4 and 8 and leave the 2. box empty since we are not given any initial conditions.
To get the general solution :
If we are given this first order homogeneous Differential Equation :
dy/dx + 5yx^3 = 0 we think of it as dy/dx = – 5yx^3 which calls for Separable Differential Equations which are solved using option 3 as follows :
Here we add an initial condition which allows to find a particular solution:
and finally the separation of variables method yields the particular solution:
To perform Integration by Parts just enter the given functions under Step by Step Integration using Calculus Made Easy at www.TinspireApps.com as shown below
Then enter given function and view steps in bottom box
When solving a Differential Equation y’=y*(5-y) , y(0)=9 numerically using the Euler Method given stepsize of 0.1 use the Differential Equations made Easy app at www.tinspireapps.com and select Euler Method in the Menu as shown below :
Now you just enter the Differential Equation in the top box and the starting point and the step size in the bottom box as shown below:
The bottom box now shows the step by step solution of the Euler Method. Works correctly for any given Differential Equation.
Alternative to the Euler Method you may also the built-in Runga Kutta RK4 method.
To solve problems involving piecewise defined functions with your TiNspire CX CAS use Calculus Made Easy at www.TiNspireApps.com and scroll down to option 9 :
Next, enter the 2 “pieces” of the function in the top box and the start/end point in the 2. box as follows :
Now scroll down to check if the piecewise defined is continuous or not. Here it is since the 2 one-sided limits match at x=2 .
Use belows Limit Solver when asked to find a constant for which a limit exists. Ex: What is a in (x^2+x-a) /(x-2) as x approaches 2?
To find the constant a for which the limit exists using the TiNspire CX CAS use Calculus Made Easy at www.TinspireApps.com , select option 6 in the Limits menu :
To solve a 3. order Cauchy Euler Differential that is Nonhomogeneous and NonLinear you would use the Differential Equations Made Easy at www.TiNspireApps.com and enter the coefficients of the Differential Equations as follows:
As can be seen, the substitution y=x^n allows us to find the zeros of the homogeneous Differential Equation and its solution below. Now, we are after the nonhomogenous solution which involves find the 4 Wronskians W, W1, W2, W3 using the Variation of Parameter method:
After finding the 3 v_i, their integration allows us to find the final solution
Puuh, that was a lot of work…If you want to skip watch all the steps you might just jump straight to the final solution.
