I have this equation which returns "Warning: Unable to find explicit solution" when i use solve on it, the equation and the variabel is symfun. And i am not sure what is wrong?
i have tried dsolve whit no luck same return.
i have tried with and without numerical values
tau_1 = diff(diff(L,diff(theta,t)),t)-diff(L,theta)
tau_m = Dm*(PS-PT)*alpha_m-Bv*diff(theta,t)
equ = tau_1==tau_m
thetadd = diff(theta,t,t);
THETAdd = solve(equ,thetadd)
and if more info is needed it can be provided
if someone have an idea it would help alot thanks
