Find the conjugate of complex number

Postby honest_denverco09 » Wed Apr 15, 2009 2:51 am

My question is that how can i find the conjugate of complex number that does not have the imaginary number or the real number part ? Do we just need to change the sign of the imaginary part in the complex number in form of a + bi to find its conjugate ? :confused:
Thank!

Is the real number like "-2" is a complex number ?
If so, What is the conjugate of "-2" ?

Add: you can always write any real number c as c+0i

or in your case -2+0i
