I would like to create a spiral with constant angle between tangent and radial line. The spiral should also start tangentially from a given circle. I would like to do it with equation.

I didn't know how to input the equation into equation driven curve.

Thanks!

Hi,

You can use the curve defined by the equation and choose equation type - parametric. The equation is x = r*cost = ae^bt *cos t, y = r*sin t = ae^bt *sin t
