I need to solve the following equation:
298082 = 250000(1 + r) + 25000(1 + r)^((365 - 258)/365)
...which simplifies to:
298082 = 250000(1 + r) + 25000(1 + r)^0.293150685
I go to SageMath Cloud and start a new project and start a new Sage Worksheet, and type the following:
x = var('x')
solve([298082 == (250000 * (1 + r)) + (25000 * (1 + r)^0.293150685)], r)
..and this gives the following:
[r == -1/10*(r + 1)^(11726006/39999927) + 24041/125000]
This is not an acceptable answer. How do I get it to solve the actual value, which is 0.089779615?MrSnrubThu, 13 Apr 2017 15:29:26 +0200https://ask.sagemath.org/question/37276/
