Question about Texas Instruments TI-83 Plus Silver Edition Calculator

Hello,

What you can do to save formulas on your calculator is while your calculator is on press the PRGM button scroll over to EDIT press ENTER then and start typing in the formulas you have (remember not to push CLEAR I learned the hard way and lost all my formulas, during my math final). While in the PRGM menu you can select NEW write a short name and press ENTER to have another area for typing (For example one area could be for Chemistry, one for Math, etc.) I hope that helps.

Here is to get you started. To increase the size of the image do a CTRL Plus (+) in your browser.

You need to calculate the slant height of the pyramid for the formula of the lateral area. You should find a value of** (1/2)*SQRT(203) **or about 7.1239 cm

You need to calculate the altitude (height) of the pyramid from the apex (summit) to the center of the base triangle (center of inscribed circle, barycenter, orthocenter). The hypotenuse of such triangle is the slant height. One leg is the altitude (to be found),**the measure of the second leg is (1/3) the altitude** **of the equilateral triangle** that forms the base. You should find (1/3) m MH= (1/3)* **(11/2)*SQRT(3)**

1. Calculate the area of the base (use a formula for the equilateral triangle or the general formula for a triangle: you have its height MH ).

2. Lateral area = 3 times the area of triangle Triangle ECD (in yellow above).

3. Total area = area of base + lateral area.

4. Volume= (1/3)(Area of base)* (height of pyramid)

If you can see the details on the screen capture below, fine, Press CTRL + in your browser to increase the size.

You cannot store permanently formulas. You can enter an equation to solve (In Equation mode). You can use the same equation again with different values but if you exit the EQAtion mode or turn off the calculator it will evaporate.

In table Mode you can enter the formula for a function and generate a table of values. For a 991ES Plus you can enter two functions. However if you change MODE everything will be erased.

In EQN (equation) there is a certain number of built in formula types you can choose. You will be asked for the coefficients which will be used to solve the equation selected. However if you change MODE your lose what you entered.**So basically you cannot save formulas to use as a memory aid **(if that is what your intention is.) Sorry.

You may be able to enter an expression in the SOLVER but it will be erased if you change calculation MODE or turn the calculator Off.

To enter an expression with letter symbols you Press the ALPHA key then the letter (A,B,C,D, X,Y).

Yes, it si possible, but as a teacher I am wary of teaching anybody how to cheat. **No reflexion on you, **If your teacher wanted to show you how to store formulas s/he would have done so. Awfully sorry.

**However, nobody nor nothing prevents you from reading the manual and learning how you do it. That is a skill worth having.**

ok. first things first, percent mens, out of 100. you simply replace the percent with fractions. say you have $400. your workers get 20% of the money made each day. 20 out of 100=1/5 of 100.so your workers get 1/5 of the money which is 400 divided by 5 wich equals 80. i hope this helps. if you still have trouble, serch on the internet for the formula for calculating percent.

Hi,

You can download the complete set of manuals available for this calculator by clicking on this**link** . There are 22 different chapters each describing a function in detail. Download all the chapters and save them for future reference.

Hope this solves your problem. Thanks

I found having formulas in the notefolio APP was easy to get to and very readable when I needed them. Cut copy and paste to home screen. If you have things in solver I just never any good at using it.
