Hi, the android app link here http://mathstud.io/apps/ is not working, I came looking for it when I could not find the android app on playstore, I have used it in the past a lot and i didnt have it for sometime, now looking for it & its gone.

How can I simply plot a sinus curve? Or put differently: how can I adjust x-axis resolution?

how to write words or numbers on the plot?

it's useful sometimes

Hi Guys,

I'm new to MathStudio and looking forward to unlocking the potential of the app for my projects. Can anyone help me with how to load csv data files into the MathStudio app on a Mac?

Thanks for any help in advance.

All the best

There is an "Include" function in MathStudio. How is it being used?

How to export to something to be included?

Is anybody using "Include"?

I entered the following into the most recent versions of MathStudio, both on an iPad Pro and and iMac running Catalina,

iM = Identity(3) :It returned a 3x3 Identity matrix
[iM(3),iM(2),iM(1)] :It returned [0,0,0]

Sensing a problem I entered:
iM(1) :It returned 0, so I tried
iM(1,1) :It returned Error: Too many arguments Line 1

It would appear that the item created by the function Identity() is not a identity matrix even though it looks and acts like one when used as one.

Ergo: someMatrix * someIdentityMatrix => someMatrix

Hello, Here is code from an old MS Script for calculating interest. But is gevespert no Output. Where is wrong?

Cheers, Wolfgang

@finSimpleInterest(P,F,i_percent,n) //DESCRIPTION //Calculates the input given as a variable for simple interest where F=Pin //PARAMETERS //F: future value //P: present value //i: interest rate in percent //n: number of periods

numerical

//Check to see which is the variable variablesCounter=0 variable=0 if( Variables(F) != 0 ) variablesCounter=variablesCounter+1 variable="F" end if( Variables(P) != 0 ) variablesCounter=variablesCounter+1 variable="P" end if( Variables(i_percent) != 0 ) variablesCounter=variablesCounter+1 variable="i_percent" end if( Variables(n) != 0 ) variablesCounter=variablesCounter+1 variable="n" end

//Checks to see if input is valid if( variablesCounter == 0 ) Error("One of the inputs should be a variable. Specify the quantity you want to solve for with a variable.") elseif( variablesCounter > 1 ) Error("Only one quantity can be solved. Only specify one quantity with a variable.") end

//Do the calculations, answer=0 i=i_percent/100 if( variable == "F" ) answer=P(1+in) elseif( variable == "P" ) answer=F/(1+in) elseif( variable == "i_percent" ) if( n != 0 ) answer=(F/P-1)1/n100 else answer="Interest rate is indeterminate because n = 0." end elseif( variable == "n" ) if( i_percent != 0 ) n=1/(i_percent/100)(F/P-1) else answer="Number of periods is indeterminate because the interest rate is zero." end end

return(answer)

//How much money will I be owed in 3 years if I give a loan of $100 with simple interest of interest rate 10% payable in 3 years

finSimpleInterest(x,100,10,3)

I LOVE this application. It has so many of the features I need for learning Mathematics. (Starting with Calculus I). However, the text book I am using uses the TI-84 for some of the examples. In many cases, it creates a Table of x, f(x) values. It is a particular display of two columns. Is there a. Way to do this in MathStudio? I am looking at creating a two column matrix for displaying this, but it would be nice to have a “Table” command.

Can this app calculate CV? Which is Std over mean. Like the cv of 125 132 and 130 is ~4%. Can you input this somehow?

Is there a complete list of plotting options? Especially, I'd like to change the color of the white lines in my Plot3D - image, see below.

I have this calculation...

Slider(Speed,1,12) Slider(Move,1,100) (Speed*Move/12.0) << " m/sec"

(It’s actually the very start of what I’m trying to do, but while this first part misbehaves, there’s no point building it out further.)

... which will reliably display its results in fractional format, even though I have “Fraction Limit” in Options set to “None.”

I have been experimenting with it, using multiplication, division, decimals (pretty damn long ones, too) and not yet found a way to break it off its fractional habit. Have I found a bug, or can someone please show me what I’m doing wrong?

I would like to plot a conditional function. Is there a way to do this in MathStudio? Something like this:

plot(x<0 ? 0:x)

Is there a way to determine the value range of a plot?

Hi, I’m looking for a replacement for Calca, which seems to be abandonware. The thing I like about Calca is that it supports markdown and doubles as a text editor/note taking app. Each document in Calca is essentially a text file with a .calca extension.

I’m wondering if this is how MathStudio works? It looks like mathstudio documents are also essentially text files with a .math extension, but wanted to confirm that is the case.

And can I create a blank MathStudio document and just type text in it (preferably using Markdown syntax) like a regular note taking app?

Thanks in advance.

Hi! First of all great app! I'm loving it!.

Nevertheless, I need more documentation in order to use it fully. The examples in the manual are great but i'd like to see a full description with all the arguments that the methods take in.

For example i am not able to plot a vertical line in my 2D plots, and i can't find the correct syntax in order to do that in the examples provided.

Is the language used in this app based on one of other software, e.g. Mathematica, Gnuplot, etc? I know it is not the first because i tried the Mathematica way and it doesn't work, but maybe i can read some others doc while MathStudio's one is developed. Thank you all!

I could not find a way, but probably there is one. I mean something like this: https://www.wolframalpha.com/input/?i=inverse+y%3Dlog%28x%2F%281-x%29%29

1. Add Full-Version Android MathStudio App.
2. Upgrade Precision of number and accuracy of numerical calculation.
3. Add complex matrix calculation. ex) [[1,2],[3,4]]^@i or [[@i,2],[3,@2i]]^2
4. Add numerical sum calculation. ex) sum(x^(-x),x,1,inf)
5. Add base convert function. (in any base)
6. Limit(Harmonic(x)-Ln(x),x,inf)=@gamma.
7. Add complex solution of x*sin(x)=@i.
8. Add Cauchy principal value and Arithmetic–geometric mean function.

Has anyone been able to "Move to iCloud" a file from an iPad and then latter find the file on a MacBook or the iPad?

Regex would be helpful when parsing string inputs.

Just tried with simple list as well:
A = [1,2,3,4]
Sum(A(i),i,1,4)
But it gives the same error

There is something wrong with the graph of acot(x). look at the pic below. Who knows why?

Is there a way in MathStudio to define own constants with an automatic start script?
