<p>I know some math but there is a part in this formula I am not sure how to interpret.</p> <p><a href="http://mathworld.wolfram.com/LogarithmicSpiral.html" rel="nofollow">http://mathworld.wolfram.com/LogarithmicSpiral.html</a></p> <p>In the first equation, is it?:</p> <p>r = a * e ^ (b * Q)</p> <p>I tried to write it as code, so if it makes sense, can you please write it the same way.</p> <p>This is what I was wondering.</p> <p>Also what are a and b supposed to be? Are these the values that define if the curves is a logarithmic curve, etc?</p> <p>Any ideas on how to get commonly used values for these?</p> <p>Lastly any code sample showing how to generate logarithmic spirals would also be appreciated.</p>
