2020-10-14 03:37:28 +0200 | asked a question | How would I transfer code from a notebook to this forum? From within a Jupyter notebook, if I do Edit > Copy Cells, followed by Edit > Paste Cells Above (or Below), it works. But Edit > Copy Cells does not copy to the clipboard in 'code mode'... It works in 'markdown mode', but the demarcation between the cell input/output is not clear. There has got to be a simple way to transfer a notebook's content to this forum to illustrate a question. What is it? |

2018-01-04 18:53:39 +0200 | asked a question | Solving an inequality symbolically under constraints Hello, new to Sage. How would you go about this problem? Assumptions: a) e0, e1 are positive real numbers b) e1 <= e0/2 Define: A=e0/2-e1; (notice, greater than or equal to zero) B=e0/2+e1; (equivalently, B=A+2e1) Solve for e1: Int(1/B)+2 >= 1/A, where Int(x) is the largest integer less or equal to x Output: An expression linking e0 and e1 |
