SOURCE: Hi, I have a Casio calculator fx-991MS giving me wrong answers!

Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.

How to use tan^2(55)


It's a quirk of notation. When a book says tan^2(x), it actually means (tan(x))^2. Only the trigonometric and hyperbolic functions seem to get written this way. If one wants the square of a logarithm, for example, one doesn't write log^2(x).

The short answer: if you want tan^2(55), calculate tan(55) then square it.

A popular question. I Googled "casio fx-55 users manual" The first link will bring you to all the casio questions on this site. Others have posted the same problem. Possibly one of the existing solutions will work for you. I don't want to steal someone's solution. Look for yourself cause it will be a specific series of keystrokes.
