Real part of symbolic complex

Hello,

how can I get real part of this:

syms u01 phiu01 R3 R1 C3 omega u02 phiu02 L1
-(2^(1/2)*R2*u01*sin((pi*(phiu01 + 90))/180) - 2^(1/2)*R3*u01*cos((pi*(phiu01 + 90))/180)*i + 2^(1/2)*R3*u02*cos((pi*(phiu02 + 90))/180)*i - 2^(1/2)*R2*u01*cos((pi*(phiu01 + 90))/180)*i + 2^(1/2)*R3*u01*sin((pi*(phiu01 + 90))/180) - 2^(1/2)*R3*u02*sin((pi*(phiu02 + 90))/180) + 2^(1/2)*C3*R2*R3*omega*u01*cos((pi*(phiu01 + 90))/180) + 2^(1/2)*C3*R2*R3*omega*u01*sin((pi*(phiu01 + 90))/180)*i)/(2*(L1*R2*omega - R1*R3*i - R2*R3*i - R1*R2*i + L1*R3*omega + C3*R1*R2*R3*omega + C3*L1*R2*R3*omega^2*i))

I got also imaginary information.

Thank you
