So the question is, is there a fast way to transform the list of equations to a matrix?Emiel ErgoSat, 20 Dec 2014 18:17:19 +0100https://ask.sagemath.org/question/25308/Solving linear matrix equationshttps://ask.sagemath.org/question/25059/solving-linear-matrix-equations/Hi everybody, I'm new to Sage and I'm pretty confused with the solving of matrix equations, I didn't fully understand the guide.
I've got these vectors:
V_fa = vector([V_f*cos(phi), V_f*sin(phi), 0])
V_ra = vector([V, 0, 0])
omega = vector([0, 0, L*psi_d])
P = vector([0, L*psi_d, 0])
And i want to implement the equation:
V_fa=V_ra+omega.cross_product(P)
to isolate and obtain the value of `psi_d`.
How can I do that?
Thank you very much
