I want to convert the following expression to form of ‘a+bi’，unfortunately，it can't be successful，Can anyone help me？

2*omega^2*B[1]*Zeta*omega[0] - omega^3*B[1]*I + omega*B[1]*omega[0]^2*I - 2*I*B[0]*Zeta*omega*omega[0] - B[0]*omega^2 + B[0]*omega[0]^2

Hi， I want to transform the formula as following，how can I do？

PS: code

(2*I*Zeta*omega*omega[0] - omega^2 + omega[0]^2)*fourier(omega[r](t), t, omega) = (omega*B[1]*I + B[0])*fourier(delta(t), t, omega)

## what is the reason?...

Maple

我计算了枫叶2019中的sin（0）和sin（pi），结果如下，是什么原因？
