Bonjour.
N-Spire CAS v.3.9.0.463
Se il vous plaît vérifier l'équation suivante:
nSolve (180 * 46.365 / 3.14 / b - 10 / (1 - cos (b / 2)) = 0, b)
Ma calculatrice ne donne pas un résultat de cette équation.
Vous devriez obtenir: 106.197
Merci.

Hi, if French is not your primary language and you feel more confortable with English, you can post it in English and we will answer you.

Perhaps your calculator is in Radians and you want it to be in Degrees ?
