# TI 84 Graphing Calculator Man.

iOS Universal Education

The TI-84 Graphing Calculator Manual app is in the TOP 25 Education in the USA!

How this app makes math so much easier:

• This manual shows all important functions of the graphing calculator TI-84 Plus, which are very useful for high school and college. Actual calculator not included!

• (Also suited for TI-83 and TI-84 Plus Silver Edition. If you have the TI-84 Plus C or TI-84 Plus CE, we have another app for this calculators).

• The app shows the exact key press sequence for 27 topics of Differential Calculus, Solve Equations, Integral Calculus, Matrices and Tips!

• You can swipe through screenshots of the original graphing calculator which show every step you have to do (220 screenshots in total)!

• Additionally there are helpful descriptions in the app which give some hints and further knowledge.

• More than 60 math problems with solutions to practice your skills!

Not yet convinced? Here's how you would benefit from this app:

• Every topic shows a detailed instruction through screenshots of the original graphing calculator TI-84 Plus which show how to solve the math problem. You only have to swipe to get the next screenshot which looks similar with your calculator display!

• To ”become warm” you have the possibility to insert a sample function in your calculator which is used in the app. The app shows an example for every topic. After that, press the first key of the respective key press sequence on the graphing calculator. Then swipe once again to get the next screenshot. It will look like the display of your calculator. The app contains for each step a picture, so it's easier to solve your math problems and become a TI-84 Plus professional.

• The app is also useful for preparing your examination, because you often don't remember all instructions of the calculator.

• Your teacher will be grateful as well, because he doesn't have to walk around the classroom until everyone's calculator shows the right solution. You only have to take a look at the app and know how to do!

• The app contains the following topics:

DIFFERENTIAL CALCULUS

• Zeros of a Function

• Y-Intercept

• Calculate Tangent
