Say your teacher has some fancy fractions to solve for you and you have a volleyball game , play practice and to prepare for the SAT next Saturday. So you take out your TiNspire CX CAS, launch the STEP BY STEP EQUATION SOLVER app from www.TiNspireApps.com and get a quick lesson on how to solve those fractions…which turns out not too difficult after following the provided steps below:
We select option 5 :
to get 5/14 . The trick is to multiply the given fractions by the product of their denominators (bottoms) to get a much easier equation to solve.
Here is another one:
It always works!
Quadratic equations can also be solved step by step. Here is one:
Even equations containing only variables can be solved (for x):
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 .
The Black Scholes Option Pricing may be used to compute the fair market value of options, its computation requires some level of mathematical analysis. If you own a Tinspire CX you can easily compute the Black Scholes Put and Call pricing – step by step – using the Portfolio Made Easy app at https://www.tinspireapps.com/?a=PIME . Just follow the steps below.
Select 1: Black Scholes : Call & Put Price
Enter the expiration date (in days), the stock price , its volatility (in %) , the strike price and the risk-free rate (in%)
Notice how the value are plugged into the Black Scholes formula. Notice how the 60 days are automatically divided by 365 days to turn the 60 days into a fraction. Additionally, the volatility and the risk-free rate re expressed as decimals.
After computing the parameters d1, d2 and the values of the normal distribution the Call price C is determined, here C = 49.4468
Lastly , the Put Price is computed, here P=37.937
The computation is easily accomplished simply by entering the given values, and it is always correct 😉
