As long no one has found a way to look at all the memory externally, we cannot really be sure if all memory is cleared. trigonometry: result of sin -1(cos -1(tan -1(tan(cos(sin(60°)))))), reference value: 60. 60.0000049383 Not only the display settings are kept, but also the last used mode is still active, but will be in a broken state. I really understand the popularitiy of this calculator in Spanish classes, I have studied ESO and Bachillerato in a highschool in a town in Málaga, and almost everyone had the fx-82MS.

I invite you to post here all your research in this model. I've splitted your post from the other thread, because it is other model. This is for organization reasons. To help the users to find your post easiliy.

This occurs because the teachers and the students don't have any knowledgment about calculators, for example, a fx-991ES plus or an used graphing calculator are cheap also(I got my fx-9750G for 3€ used), and have many functions more.

calculation with percent +/- change sign (direct entry of negative numbers) RV exchange registers (X-Y) F floating-point notation Fix fixed-point notation: the listed decimals can be chosen (0-9) Sci scientific (exponential) notation Eng engineering notation a b/ c allows entry and display of fractions Sqr square root x 2 square pi value of pi (3.1415..) can be recalled 1/x reciprocal trig trigonometrical functions (sin, cos, tan and inverses: arcsin, arccos, arctan) hyp hyperbolic functions (sinh, cosh, tanh and inverses: ar sinh, ar cosh, ar tanh) DMS-DD conversion of decimal and sexagesimal numbers log exponential and logarithmical functions (10- and e-base) y x raising to power SD one variable statistics: calculating mean and standard deviation nCr probability calculations P-R converting coordinates between rectangular and polar systems n! factorial Its TABLE FUNCTION makes graph work a cinch. No more tedious, error-prone evaluation of functions. This obviously means that more time is spared to teach the Math behind the graph. Yo PPL, it's been 4 months from the last reply and I hope y'all safe and sound. I really thank this team for its Intel.Not only the display settings are kept, but also the last used mode is still active, but will be in a broken state."
