请求Matlab高手帮忙，用matlab求g(x)=[e^(-5x)]cos(2x+1)+5微分方程，请给详解，谢谢

Question

请给个计算过程和结果，十分感谢

Answer 1

g = sym('exp(-5*x)*cos(2*x+1)+5');
Gx = diff(g, 'x');
Gxx = diff(Gx, 'x');

dsolve('D4y+10*D3y+35*D2y+50*Dy+24*y-(5*(21*exp(-5*x)*cos(2*x+1)+20*exp(-5*x)*sin(2*x+1))+4*(-5*exp(-5*x)*cos(2*x+1)-2*exp(-5*x)*sin(2*x+1))+2*(exp(-5*x)*cos(2*x+1)+5))', 'x');
