Given the direction of full dip and the rate and direction of an apparent dip of a plane or seam, find the rate of full dip.
Full dip direction = α
Apparent dip direction = β
Apparent dip rate = 1 in y (AC = y)
Full dip rate = 1 in x (AB = x)
In triangle ABC:
cot full dip (1 in x) = cot apparent dip (1 in y) X cosine angle between full dip and apparent dip (β-α)
