What I achieved so far:

The tutorial I'm following:

Where I'm stuck:
Adding the tangent node doesn't result in the spiral effect as shown in the Tutorial here

What I'd expect:
Adding the tangent node results in spiral effect
You can combine a radial effect and a wave effect:

The disk is Z up, its radius is along X and Y.
The generated coordinates are centered to -0.5 to 0.5.
The wave is to have a sinus going along the radius, from the center to the edge.
The radial effect is to have a cosinus depending on the angle around the disk.
