Hello community, to automate my calculations I would like to save results of a spreadsheet calculation as seen below to compute at display the results of further calculations with sagetex. How could I save the data from a spreadsheet to use them with sagetex? What for a data-structure/type would you suggest? 2013-04-29 11:53:50 -0500 marked best answer SAGETEX: Howto compute solution of a function First, what do you want to solve? It's a function, not an equation. Do you want to solve loesung(lambda_z, s_k) = 0? Do you want to compute loesung(5, 4)? Second, I believe that the line defining loesung will overwrite the previous definition of lambda_z, making it a symbolic variable instead of just being 5. So perhaps: \begin{sagesilent} lambda_za = 5 # note the 'a' at the end s_ka = 4 loesung (lambda_z, s_k) = lambda_z * s_k \end{sagesilent} $\sage {loesung }$ This will print out 20: $\sage {loesung(lambda_za, s_ka) }$ 2013-04-29 11:53:50 -0500 received badge ● Scholar (source) 2013-04-29 10:25:09 -0500 received badge ● Student (source) 2013-04-29 09:42:48 -0500 answered a question Human readable representation of formulas Thank you for your response to my question. Output with your notation: f(h)=19/100+(91/100)*((h+140)/760)^2 --> 91/57760000*(h + 140)^2 + 19/100 Other example: S(A) = (0.25+1.91*((A+140)/760)^2) >= 0.85 --> (3.30678670360111e-6)*(A + 140)^2 + 0.250000000000000 >= (17/20) S(A) = (25/100+191/100*((A+140)/760)^2) >= 85/100 --> 191/57760000*(A + 140)^2 + 1/4 >= (17/20) Is there a other way to display the same formula as programmed, because for a quick review the output is not handy? 2013-04-29 06:55:02 -0500 asked a question Human readable representation of formulas Hello, i do have question regarding the representation of formulas in sage. Is a formula typed into sage, the routines will transform the expression, which could be less human readable. How can I programm sage to use the typed in formula and still compute a solution? Example: f(h)=0.19+0.91*((h+140)/760)^2 will be transformed to (1.57548476454294e-6)*(h + 140)^2 + 0.190000000000000 Sincerely 2013-04-23 08:49:47 -0500 asked a question How to display a function with the values of the variables? For the generation of worksheets I need to know, if its possible to show a function with the assigned values? What could be a process to do that? My hope is to generate a output like: (lamda_z,s_k) |--> lambda_z * s_k = 5 * 4 = 20 \begin{sagesilent} tension (lambda_z, s_k) = lambda_z * s_k lambda_za = 5 s_ka = 4 \end{sagesilent} $\sage {tension (lambda_za, s_ka)}$ \end{document} thank you 2013-04-22 11:08:42 -0500 answered a question SAGETEX: Howto compute solution of a function Thank you, that was helpful. To finalize my project one last question: How can I display the values of the variables in the function? Like: f(lambda_z, s_k) = lambda_z * s_k = 5 * 4 = 20 2013-04-22 10:19:10 -0500 received badge ● Supporter (source) 2013-04-22 05:53:09 -0500 received badge ● Editor (source) 2013-04-22 05:50:37 -0500 asked a question SAGETEX: Howto compute solution of a function Hello, how can i display the solution of the following function with sagetex? \documentclass[11pt,a4paper,landscape]{article} \usepackage[utf8]{inputenc} \usepackage[german]{babel} \usepackage{amsmath} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{sagetex} \usepackage[left=10cm,right=2cm,top=2cm,bottom=2cm]{geometry} \author{} \title{Vordimensionierung Hallentragwerk} \begin{document} \begin{sagesilent} lambda_z = 5 s_ka = 4 loesung (lambda_z, s_k) = lambda_z * s_k \end{sagesilent} $\sage {loesung }$ \end{document} Sincerely reb_reb
