2021-01-14 16:25:07 +0200 | asked a question | Simple trigonometric equation solving I was a MapleV user in the past (~25 years ago) an I'm very pleased to find such an elegant solution the sage is. I try to see how it works trying to solve an easy trigonometry calculation: Do not want, ok. To simplify I put some real values m and l and tried again: still not solving, r=3.68357 is what I'm searching for. What would be a right way to proceed? Thank you in advance, v42 |
