Situation 4 Mean Exit Time to One of the Slices

If the separation of the particle is not on one of the slices (as in Fig. 4.9), then the required time to reach one of the slices is obtained by solving Eq. (4.103), without the assumption that r = (A + B )I2. One such method is to approximate the sinh term to second order to give the general solution 

The algorithm to generate an exponential time with the above mean using a uniformly distributed random number C/(0,1] is then simply
