equation = -0.4787 + 7.3246 * (3.14 * 0.05/x) +0.3963 * (3.14 * 0.05/x)^2 + 15.613 * (3.14 * 0.05/x)^3 +(1j * (266.265 * cot (0.05 * 3.14/x)- .4456 +17.0082 * (0.05 * 3.14/x)- 8.6793 * ((0.05 * 3.14/x)^2) + 9.60131 * ((0.05 * 3.14/x)^3)) =144.3
i need to plot frequency which is
f= 3*10^8/x

Is the "1j" intended to represent the imaginary constant? If so then is x itself intended to be a complex number, or is it expected that the imaginary portion will resolve to be 0 ?

If the "1j" is intended to represent the imaginary constant, then the equation has no real-valued solutions. The real part of the equation has a singularity at x = 0, at which it switches from always negative to always positive, no zero crossing.

You can not plot it. The lay out of your problem is not right. Your equation has zero crossing (=solution)according to Walter Roberson. What are you going to plot against what?
