You cannot use the two words in the same sentence. To use the hyperbolic functions, press the HYP key. The display will show you what follows.
1: hyperbolic sine, 2: hyperbolic cosine, 3: hyperbolic tangent, and their inverses.
To calculate the hyperbolic cosine of the number 27/3, press 1 in the first screen capture, you get cosh(. Complete the expression and press=

Binompdf ( says n:......p:.....x:..... How can I enable this guided input on my TI-84?


In the older versions of the OS, the command binompdf( displays a command line where the user is expected to enter the arguments respecting the syntax of the command. In the more recent versions of the OS (the most recent is 2.55 MP) the user enters the input over three lines.
I suggest you upgrade the OS of your calculator to the latest version available on the education.ti.com website.
To upgrade, insert fresh AA batteries (or just good batteries), run TI connect on your computer, connect the calculator to the computer and click the update button on TI connect main screen. It will download and update the OS.

Can i calculate calculus using fx-991ms


If you want to get an answer like 1/2X for d/dx(X^2), you will have to purchase a CAS calculator like Casio's Algebra FX-2 or Classpad. TI series calculators also have CAS.
However, you can calculate the numerical values of derivatives and integrals only.
To calculate the value of a proper integral:

  1. Press the 'ON' key;
  2. Press the Integral key b8325f5.jpg;
  3. Enter your expression (example X^2+X-3 etc);
  4. Press the 'comma' key after your expression;
  5. Input the first limit after comma, input comma again after first limit;
  6. Close brackets;
  7. Press the equals key, display may return after a while with the answer.
for eg to calculate xdx from 0 to 2, input as follows:

dx(X,0,2)

To calculate derivative at a point:

  1. Press Shift and then the integration key.
  2. Enter your function;
  3. Input comma;
  4. input the point at which you want to evaluate the derivative;
  5. Close bracket and press enter.
Example, to calculate d/dx X^2 at 3 input:

SHIFT+dx key X^2,3)

Display looks like this: d/dx(X^2,3).

Hi i have the canon p170-DH and i cant subtract. example: 4-4= -8 not 0


Hi....by looking at the date you posted this question, you may have already found the answer, but just in case you haven't......the procedure for adding and subtracting on these calculators is completely opposite of a regular calculator. On a regular calculator, you would input 4 - 4 = 0. On these type of calculators, a number's positive or negative status is keyed in AFTER the number, instead of before it. Therefore, you input 4 + 4 - (notice you DO NOT input = at the end, but if you are in print mode, you will need to hit your total key, which looks like an asterisk, where the = would normally be, in order for the final value of your calculations to print on the paper tape.

Multiplication and division equations are done exactly as they are on a regular calculator....4 x 4 = 16.

Hope this helps. If you have your owners manual, it should also give you some examples of how to perform calculations with your calculator.
