Using the Electrical Engineering Made Easy using the TiNspire CX calculator at https://www.tinspireapps.com/?a=ELEME we added functionality for AC Circuits. Look at the images below. In particular, the single phase and the 3 phase ALL IN ONE Solver come in very handy.
Given a Discrete Probability Distribution such as the one shown below make sure that the sum of the given probabilities is 100% or 1 . If you own a TiNspire CX you can enter the distribution in the top two boxes of the Statistics Made Easy App available at www.TiNspireApps.com .
Once done you get the expected value , variance : step by step. Optional is the value of N which allows to compute P(X>N) , P(X<N) etc
For a uniform distribution , you enter the given interval [a,b] and the value c which lies on [a,b] . You will then find P(X<c) and P(X>c)
The Numerics Made Easy app at www.TinspireApps.com was updated to also solve the following concepts:
Secant Method to find zeros of a function Jacobi Method to solve A*X=B Cholesky Decomposition Newton Method for Interpolation Orthogonal Polynomials: Legendre , Hermite, Chebyshev and Leguerre 3-8 Simpson Rule Newton Cotes
Computing the Volume of a Solid of Revolution using the TiNspire CX CAS can easily be done – step by step – using the Calculus Made Easy at www.TinspireApps.com .
Here is how.
Let’s start with the Disk Method. We just select that option in the menu:
Then this pops up :
Now, enter the given function in the top box and the given interval below. Automatically, the answer will show in the bottom with correct integral setup and the correct answer.
Similarly, when using the Washer Method for two functions we have:
Finally, the Shell method works the same way :
In conclusion, the just like all other Calculus topics finding the Volume of Solids of Revolution using the Disk , Washer and Shell Methods can be done easily using Calculus Made Easy at www.TiNspireApps.com .
