Correct target calculations for given slab thickness

Drilling angle

Target depth at which hole intersects crack for given slab thickness b

Minimum drilling depth (b min)

Maximum drilling depth (b max)

Distance (a) from hole entry point to crack

The size of the limit of correctness

Height at which hole intersects crack for a given distance of hole entry point from crack (calculate b)

Does the drill intersect the crack within the slab?
