eqq0: V_f*cos(delta(t))=v(t)
eqq1: V_f*sin(delta(t))=l*diff(psi(t))
I need to isolate V_f from the first equation, obtaining V_f=v(t)/cos(delta(t)) and substitute it in the second equation. Then i have to isolate diff(psi(t))=[v(t)*tan(delta(t))]/l.
I did :
a=solve (eqq0,V_f)
V_ff=a.right()
but it says *"AttributeError: 'Sequence_generic' object has no attribute 'right'"*
How can i solve this two equations?
Thank you.
