I'm trying to find the formula to plot the following spiral:
It grows at a rate of √2 for every 45 degrees of rotation, so for example starting at 0 degrees (at 45 degree increments), it expands thus:0, 0.7, 1, 1.41, 2, 2.82, 4 etc... But I want to be able to find the distance from the centre at any angle, not just at the 45 degree increments.
Can anyone help with this please?
Many thanks
