Boundary and inital conditions: C=Co , t=0, 0<=x<=inf. C=Cdf x-> inf , t >0 P=Po , t=0 0<=x<=inf. P=Po t>0 x-> inf. P=Pw x=0 t>0

Hi The equation is: \frac{dP}{dt}-A*\frac{{d}^2P}{dx^2}-B*\frac{dC}{dt}=0 dP/dt=A*d2P/dx^2 was solved using a finite difference method. If the function C(x,t) is known, is it possible to solve the whole equation by using the finite difference solution as a supplement to the complete solution...

Hi. So a classic logic puzzle goes like this: At noon the hour, minute, and second hands coincide. In about one hour and five minutes the minute and hour hands will coincide again. What is the exact time (to the millisecond) when this occurs. (Assume that the clock hands move continuously.) If...
