. 8080 Answers SOURCE: Hello, It may be due to the angle unit used. You can have angles in degrees, in radians, and in grads. You should set the default angle unit to waht you problem calls for. To set degree as default SHIFT MODE 3 To set radians as default SHIFT MODE 4 To set grads as default SHIFT MODE 5 The values of angles calculated by the inverse trigonometric functions are in the default unit that is set. This may be the source of the wrong answers that you get.

I'm new to this forum!.I arrived this site by surfing in the web looking for an answer, I hope to find it here. I'm about to buy a new scientific calculator, the problem is that I don't know the difference between two models.These are casio Fx 115 ES and casio Fx 991 ES. I downloaded the manuals (they're the same) but.is there any difference between these calculators?.I hope you can tell me Well That's all.Thank you very much in advance DariosI don't know why but they sell them as? X-991ES in Europe and as?x -115ES in the USA. As far as I know, the difference is only in name, not in function.

HOW CAN I DO WITH CALCULATOR CASIO FX 991 THIS OPERATION?? A-A^-1 1 2 3 4 5 6 7 8 9 THANK YOU!!For - use 'STO' key For ^ use 'xlittle square' key (left of the log key) For - use the key with '(-)' on it. Rest is same.

Hey, I'm new to this forum. Umm im having trouble with the fx-991. I am unable to perform the calculation of 6x10-11 (6 to the power of -11) minus 5. The answer shows up as 5. I've tried that with any other number in exponential notation and the answer is the answer of whatever number im adding. Can anyone tell me how to fix that.

Well, the answer would be -4.4 which rounds to -5 on any calculator that displays less than 12 significant digits (the vast majority of calculators). Try 6x10^-2 - 5 and you'll see that the calculator processes this correctly. Hello, I have a fx-115ES.

I have been trying to figure out how to find the derivative. I know that the manual has some brief and ambiguous instructions on how to do so, but it's not that intuitive for me. I was wondering if anyone here knows how to accoplish this. What i am trying to do is calculate the slope of a tangent line on any given point on the function, instantaneous rate of change, or derivative. Somehow the the calculator must be able to do the following. Calculare the and simplify the difference quotient 2. 001 files how to open.

Find the limit as h approached 0. In the top left of the keypad i see the d/dx button (it's a shift to get it to pop up). At that point it as for some fields that i am not familiar with.

Can anyone kindly help?
