Run that equation in a mathematical software. Get as many X,Y data points as you want for the smoothness of the curve. Use those data points in the curve by table command.
A curve table is probably the fastest method, but you might also be able to create it with construction geometry. I created an involute curve once using this method. Since an involute can be defined as the path traversed by a point on a string as the string is unwound from a circle, I mimicked this in a sketch. The trick was using the variable table to make the "string" segment lengths equal to the corresponding arc lengths. You could incorporate your equation in the variable table.
Yes, I can descibe how to construct it. However it would be better if I could post a jpeg image or a dwg file. It is easier to see how it is done.
Does anybody know how to post a file?
