| It did not occur to me the use of recurrence relations.Thank you very much Sir for the guidance. Regards. |
| Thanks Horvat, In fact I have found a way to get the coordinates of a triangular mesh of any size as described earlier without the graphical representation. My interest is to count the number of all equilateral triangles so formed by these... |
| Thanks all for the help. |
| We may use Reduce[Abs[x + y] |
| Since square root function does not automatically simplify Sqrt[x y}] to Sqrt[x] Sqrt[y],we may use the PowerExpand code: $Assumptions = c \[Element] Complexes; PowerExpand[Sqrt[1/(c + Coshl)] Sqrt[(c + Coshl)/(1 + c)]] // Simplify ... |
| Thanks Milton.Its easy to remember. |
| Hello Frank, Thanks a lot. It helped me write a code for simplex method in OR. |
| Hello Friends, Can we have a Year (0) and negative years such as Year (-1) for BC Years? I have a program (attachment given) to find calendar for any year (be it positive, negative or zero). But it conflicts with the Wolfram calendar for Year... |
| Hi The code to be written is as follows with "," without "=" sign Sum[Sum[1, {j, i + 1, n - 1}], {i, 0, n - 2}] |
| Hi Manuela, You can try: Integrate[ArcTan[x] /(x Sqrt[1 - x^2]), {x, 0, 1}] // TrigToExp |
