A little help with a math problem....
Hallo can any of you do some math...:-)
I have a problem I just can not solve, 1) I need to find a and b in the formula 2) find the direction and radius then Peter has "worked" 3 km arc line Peter must treasure hunt in the woods and have been told that he can find the treasure to closely follow the path of a logarithmic Spira, at a given starting point. If he walk 3 km, on the arc line. He will find the treasure. Peter knows a logarithmic spiral is as follows:  Startpunkt=STARTPOINT He has also been told that when he has revolved around 180 degrees (marked with A in the figure), he is 86.23 meters from where he started, and after 360 degrees (marked with B in the figure), he is 75.41 meters where he started. Fortunately, Peter also knows the formula for a logarithmic spiral:  , and he assumes that the starting point corresponds to Theta = zero. With this knowledge puts Peter down first and count (long) on the figures. Then he prepared for the trip, and he does not actually become dizzy by. Taygoo - Have tried to solve this in days now...:-)

This isn't a math question! It's a conspiracy!
Why is Peter being forced to "treasure hunt"? Who is forcing him? Why does he believe that he will find treasure if he goes in such a way? Peter is clearly being manipulated by a shadowy group with evil intentions, I say, and it's same group of shadow-dwellers that want us to focus our concentration on him rather than to see the truth! Rise up! Rise up against the evil conspiracy!

Ack.
It's calculus...rectification/integration. I'll give it a bash, but I am also new to think kind of thing. If I don't reply soonish assume that it has induced brain paralysis in me...
