2018-11-25 15:55:54 +0200	asked a question	Solving Sytem of Equations with Trig Just trying to solve a system with approximate results, but I am getting an error. Code: Fs, Na, Nb, theta = var('Fs Na Nb theta') eq1 = 0 == Fs + 0.16Na - 10.0sin(theta) eq2 = 0 == Na - 10.0cos(theta) eq3 = 0 == 0.26Nb - 6.0sin(theta) - Fs eq4 = 0 == Nb - 6.0cos(theta) solns = solve([eq1,eq2,eq3,eq4],Fs, Na, Nb, theta, solution_dict=True) [[s[Fs].n(30), s[Na].n(30), s[Nb].n(30), s[theta].n(30)] for s in solns] Error: KeyError Traceback (most recent call last) <ipython-input-27-8201f1ef9ddf> in <module>() ----> 1 [[s[Fs].n(Integer(30)), s[Na].n(Integer(30)), s[Nb].n(Integer(30)), s[theta].n(Integer(30))] for s in solns] KeyError: Fs Any advice?? I am new to Sage. EDIT: Fixed the code I posted so it is more readable. Still looking for help on this. Thanks!
