The basic quiz concentrates on the trigonometry of right-angled triangles:
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
The advanced quiz concentrates on the trigonometry of non right-angled triangle. Specifically, the following rules:
The sine rule: a /sin A = b / sin B = c / sin C
The cosine rule: a square = b square + c square - 2 bc cos A
The area of a triangle: 1/2 * ab * sin C
where a, b, c are the three sides of a triangle, and A, B, C are the sides opposite to the angles.
