Hello this might seem annoying but is there a way to export that derivative data into a CSV?

@slelievre I entered as many data points there is just a lot more data.

@slelievre Ok I will, it keeps saying greater thaan 60 points to upload file....

I am trying to get the derivative of this CSV data set, and this is code I have so far I thought it would be similar to this matlab code:

dy=diff(y)./diff(x)
plot(x(2:end),dy)

Data Set:

0,2.58612
0.00616025,2.20018
0.0123205,1.56186

0.0985639,0.096153
0.104724,0.216782

There's more data...a lot more This is my attempt at the code:

import csv
data = list( csv.reader(open('C:/images/TEST1.txt','rU')) )
data = map(lambda x: [float(x[0]),float(x[1])],data)
P = list_plot(data, plotjoined= True, color = 'blue', xmin = 0, xmax = 3)
TeraHertz = text('Tera Hertz', (1.5,-.9)) 
Absorbance = text('Absorbance', (0.8,5))
g = P + TeraHertz + Absorbance
g.show()
latex(g)
g.save('TeraHertzTEST1.pgf')
t=diff(x[1]).diff(x[0])
l = plot(x[0],t)
l.show()

The directory where kpsewhich -var-value=TEXMFHOME the command takes me is not real in my commuter. I am using this help this one

because the mismatch occurred any clue to how I could change that directory to something else and get sage tex working?

C:/Users/Light_Wisdom/texmf False Directory.

I have this question and I downloaded sagemath and I have three applets a console, a shell, and a notebook, and I was wondering how do I do what the person did because I tried the shell multiple times and I moved the sty file into the Latex folder anything I can do to help you help me please let me know? The error I keep getting is this error file not found.

I want to latex out the figure that is done in the graph?

Its ok I am just going to delete the question I realized the error.

I have been getting this error UnboundLocalError: local variable 'xmin' referenced before assignment and I have been wondering why the error is present. And how I could fix it to get the LaTex for it.

Sage: from sage.graphs.graph_plot import GraphPlot
Sage: options = {
....:   'vertex_size': 200,
....:   'vertex_labels': True,
....:   'layout': None,
....:   'edge_style': 'solid',

Sage:xmin = -10 
     xmax = 10
     f = plot((x^2-2)/(x+2), (x,xmin, xmax), ymin = -20, ymax = 20)
     pt1 = point((-2,2), rgbcolor='blue', pointsize=40)
     z = Graph((f+pt1).show(xmin= xmin, xmax= xmax, ymin=-20, ymax=20))
     GP = GraphPlot(z, options)
Sage:z.set_latex_options(
....: graphic_size=(5,5),
....: vertex_size=0.2,
....: edge_thickness=0.04,
....: edge_color='green',
....: vertex_color='green',
....: vertex_label_color='red'
....: )
Sage: latex(z)

Yes I reran the code, and it worked fine.

Too many arguments, and that it only accepts 1.

This function is seemingly not plotting and it keeps saying theirs too many arguments in the 2nd line. Any thoughts...

f = (1*x^2-2)/(1*x-2)
plot(f, x,-10,10)

I have the following code and I am trying to get an output, and I keep getting an error y is not defined. Could you please help?

 var('y')
 f = sage_eval(str(input("What is the function:" )), locals = {'y' == y})
 integral(f,y,0,16)
