The spiral has the property that the angle φ between the tangent and radial line at the point (r, \theta) is constant. This property can be expressed in differential geometric terms as
The way it is done is, you take values for θ and calculate the value of r you get.
is there any particular formula?
θ is just a variable, similar to x in y=x^2.
in polar coordinates, the logarithmic spiral is given by r=ae^(bθ)
