What are the steps to create a histogram on this calculator?
SOURCE: No decimal display on TI BA-II calculator
Your BA II PLUS stores numeric values internally to an accuracy of 13 digits. However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][3][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.
SOURCE: nPr and nCr key
Hello,
On calculators you calculate permutations and combinations as follows
Enter the number n then press key nPr, and the number r
18(nPr)5=1028160
For combinations, use nCr key instead of nPr.
18(nCr)5=8568.
Hope it helps
SOURCE: Using e on the BA II plus financial calculator
Hello,
To use the exponential function, you must enter the number then press [2nd][e to the x] or [e^x] for short.
e^(-0.1) is entered as (-)0.1 [2nd][e^x], where (-) is the change sign key
You will need to use extra parentheses to avoid errors.
20 - 18*( (-)0.1 [2nd][e^x] ) [=]
The Minus sign between 20 and 18 is the regular one. The (-) before the 0.1 is the change sign key (-) or sometimes labeled +/-. The asterisk is the multiplication sign.
Hope it helps.
SOURCE: is it possible to calculate cube root or higher
To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.
it gives the cube the 4th power, 5th, 6th, etc.
If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.
When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.
The syntax of the command is value [Y to x] (1/ order of root)
Ex: cube root of 27 is entered as 27 [Y to x] (1/3)
