I am stuck on the following task;

Create a 2D Parametric Plot showing a spiral path. The parametric equations for a logarithmic spiral are x=k^u Cosine(u), y=k^u Sine(u), where k is a constant, and u is the plot parameter. What does the value of k determine?

I have been typing in the following but it is wrong

ParametricPlot[{(k^u)*(Cos) /. {k -> 1}}, {(k^u)*(Sin) /. {k ->
1}}, {u, 0, 6 Pi}]
Can anyone help?

much appreciated

No worries peeps, I figured it out, just had some dodgy brackets about!
