Dear Matlab users,

Matlab says "Cannot find explicit solution" . Can anybody solve my problem?

syms A delta phi w w0 Tmax Yf

eqn = Yf ==(A*(delta*cos(phi) + w0*sin(phi) + w*cos(phi)*1i))/(delta^2 + delta*w*2i - w^2 + w0^2) + (A*exp(-Tmax*delta)*(sin(Tmax*w) + cos(Tmax*w)*1i)*(delta*cos(phi - Tmax*w0) + w*cos(phi - Tmax*w0)*1i + w0*sin(phi - Tmax*w0))*1i)/(delta^2 + delta*w*2i - w^2 + w0^2)

sol_4=solve(eqn,Tmax)

sol_1=solve(eqn,A)

sol__2=solve(eqn,delta)

sol_3=solve(eqn,w0)

Warning: Unable to find explicit solution. For options, see help.

> In solve (line 317)

Thank you
