syms ksi a1 P A N L h0 c r mu f1_(ksi)
w_ = A*cos(P*ksi);
f0_(ksi) = a1*cos(P*ksi);
equ2_right = 2*N^4*cos(P*ksi)*f0_ + N^2*P^2*mu*cos(P*ksi)*f0_ - 2*N^2*P*sin(P*ksi)*diff(f0_,ksi) + ...,
P^2*cos(P*ksi)*diff(f0_,ksi,2) - 4*N^2*cos(P*ksi)*diff(f0_,ksi,2) + 12*c^2*r^2*L/h0*cos(P*ksi)*...,
diff(w_,ksi,2) + 2*P*sin(P*ksi)*diff(f0_,ksi,3) + 2*cos(P*ksi)*diff(f0_,ksi,4);
equ2_left = diff(f1_,ksi,4)-2*(N^2)*diff(f1_,ksi,2)+(N^4)*f1_;
solve(equ2_left == equ2_right,f1_)
