I have an equation: 1 + ( 9 / ( s*(s + 9) ) )*( k/(s + b) ) = 0; where s = -2 + i*2 (i is the complex number). I know it can be solve by separating into real and imaginary parts, substituting the value of s and then equating both equations to zero and solving the simultaneous equations to find the values of b and k. but how do i make Mathematica do this for me cause it takes very long on paper.
thanks heaps guys
