Littlelostattimes Posted November 11, 2015 Report Share Posted November 11, 2015 Hi there,I was wondering if we could all make a post about the commands for calculators used for solving maths questions. Some of us might forget about them but I think making a generalized list for this would be great(?) The list I had in mind would be like: The calculator's model The math topicCommands to solve for the math equations related to the topic Ex: TI- nspire Basic commands1. Menu>>> 2. Number >>> 1. Convert number to decimals Statistic and probability1. Menu>>>>5. Probability >>>>1. Factorial (!) These are more straight forward but there may be different ones that do not directly show that it is related to other topics I'm not sure if this is useful but sometimes my maths teacher assumes that we know how to work our way with the calculator and there are also times when all of us struggled in class so this led me to think about starting a topic for this. I'm hope I wasn't bothering anyone I would be adding more commands as I learnt from my class if this is interesting. I just think that it would be great for me and others who will be taking the exams to look for the commands in one page for their calculators. Cheers! 1 Reply Link to post Share on other sites More sharing options...
kw0573 Posted November 11, 2015 Report Share Posted November 11, 2015 (edited) Yeah definitely keep a small notebook for all the commands.You should, for the core topics (I don't know if you are Studies, SL, HL, or Further), be able to do the following on your calculator if and when you learn these topics- all distributions and combinatorics functions / producing Pascal's triangles- finding mean, standard deviation, variance, range, sum of values^2, for individual data or grouped data; producing a graph - arithmetics with complex numbers in both rectangular and polar forms- Derivatives and definite integrals from graphs and from direct input- Graph analyses (find max/min, evaluate, graphing derivative functions, changing the zoom, setting bounds, zooming at a specific value)- Change display (dashed, dotted, bolded, etc) for graphs so you can distinguish multiple graphs plotted together- switch between radians and degrees- Find (real) solutions to equation or system of equations (graphs; direct input; row reduced echelon forms for intersection of planes) - plot non-function relations, parametric curves, piecewise functions- any additional requirements for paper 3, such as graphing sequences and series or more statistical analyses Edited November 11, 2015 by kw0573 1 Reply Link to post Share on other sites More sharing options...

I'm really glad I posted about it, your list is awesome and detailed! I realized a few problems though, I really do not know when to switch between radian and degrees. The funny thing is when I asked my teacher said you just gotta know, if the answer looks weird then switch it around. Well that is confusing, luckily you reminded me how important it is, I hope someone could tell me that ^^. I'm gonna make a list for myself in my book now of the commands. I would love to share it with everyone when I found lots, it would be great to be helpful to people who struggle with calculator as much as I did. Thanks kw0573!!!! Btw, I'm doing maths HL and I'm kinda struggling with it but lately I'm improving in calculus too! So I'm gonna work hard on mastering the calculator for paper 2 and 3 Reply Link to post Share on other sites More sharing options...

El :3 Posted November 12, 2015 Report Share Posted November 12, 2015 If you're doing the HL calculus option, know how to do Euler's method on your calculator - it saves your life! Reply Link to post Share on other sites More sharing options...
