Setting the domain for a graph of a function on a Casio fx-CG50 Calculator

[@TheCalculatorGuide]

Thanks to do_math_4_life for discovering this.

[@timotheospetros]

Great stuff. Note that one of the two limits can be omitted, although the comma must still be included. In the multipart function at the end, for example, one could just write [ ,1] for the first function and [1 , ] for the second.

[@TheCalculatorGuide]

Thanks for this. Great info.

[@TheEngineerBlueprint]

Nice to learn new tricks :) Thank you!

[@daisybrown4995]

How do you get the scales to show. I have the grid but no numbers/co-ords?

[@N9TheNoob]

me too

[@LiamBavingtonHodge]

Do you know how to set the domain for parametric curves?

[@akfig184kdk]

thanks a lot, this is so helpful. by the way, how do you make it show up the blue grids? on mine, there's no gird but scales.

[@TheCalculatorGuide]

SHIFT, SETUP, GRID, Line

@@TheCalculatorGuide thank you so much i though i was the only one who didnt know and then i find it on some 2 year old comment

[@ToonOfLancing]

Another gem! Thank You.

[@seungwonlee4449]

how do you get the numbers to display on the axis? 1,2,3,4 etc.

[@TheCalculatorGuide]

I have the following settings in SETUP Coord: On Grid : Line Axes : Scale Label : On

[@AlexRider5601]

How do you do this for parametric equations?

[@TheCalculatorGuide]

I'll have to look into that.

Great video. Thanks It's a shame such aan expensive calculator does not have equals to or less than (or more than) symbol in its daatabase. Casio Classpad does, and since much of the software is same, they could have included this.

[@CynSw]

Less than, more than and equal to can be represented by normal and square brackets (bracket and meaning respectively) ( and ) are more than, less than [ and ] are more than and equal to, less than and equal to You can combine them like this: (0, 5] is more than 0, less than or equal to 5 and so on I hope this helps

@@CynSw Hi Cyn, thank you for your reply. Does not seem to work for me...tried it.

[@leonhardolaye-felix8811]

@@AceOfHearts001you can use [5,] to show more than 5 or [,5] to show less than 5. Idk if that’s why you meant though

[@nighttrain1236]

I didn't realise you were in radians initially lol.

[@marvenus3628]

@The Calculator Guide, hello! Could you make a video on how to draw an implicit differentiation graph on CASIO fx-CG50.🙏

[@TheCalculatorGuide]

I’ll put it on the list.

[@marvenus3628]

Thank you very much!🍀🌞

[@johnsergie3906]

Hi Do you know how I would draw the line 10x+2y+11 on the CG50 Thanks

[@TheCalculatorGuide]

Simplest way would be to rearrange to y= mx + c form 10x + 2y +11 = 0 2y = -10x -11 y = -5x - 6.5

[@kafikfishna8806]

What if 1 is NOT in the domain of X? How can we draw that and find the range? What if our conditions are X1 only? There is NO closed interval.

[@TheCalculatorGuide]

I imagine that would be too hard for the calculator as potentially you could reach values of up to infinity. I'll double check, but I am guessing it is too much processing power. If anyone knows then do comment below.

What is a Ma error, and how to fix errors

[@veem3150]

Excellent explanation indeed. Thank you so much for all the effort you put into the production of these videos. Quick question if I may. In your first example of plotting sin x, is there a way of configuring the calculation so that the units on the x axis are given in terms of pi? Results in your example give the x-axis domain as -3.1 < x < 3.1. Also can you configure the plot to provide finer granularity on the x and y axes e.g. -pi < x < pi in steps of (say) pi/4? Many thanks for any advice. VBR Vee

[@TheCalculatorGuide]

I don't think there is or at least i have not yet found out how. It would be very useful though!

[@veem3150]

@@TheCalculatorGuide Many thanks for replying. Please let us all know if you DO find a way; I'll do likewise :-)

[@fishwishpishpish9165]

can you also define the range? thanks

[@laithaljaber8051]

Do you know how to now ?
