MATLAB: Error using sym/sin : Too many input arguments

Question

clc;
syms w k c m F0 t
w_n = (k/m)^(1/2);
zeta = c/(2*w_n*m);
A = F0*(k-m*w^2)/((c*w)^2 + (k-m*w^2)^2);
B = F0*c*w/((c*w)^2 + (k-m*w^2)^2);
x = A*cos(w*t) + B*sin(w,t);
xd = jacobian(x,t);
xdd = jacodian(xd,t);
Dynamic_Differential_Equation = m*xdd + c*xd + k*x

Answer 1

x = A*cos(w*t) + B*sin(w,t);
                        ^---- should be *
