What is 'differentiation'?
Differentiating a function, f(x,t) with respect to a varible, such as x or t, tells you rate of change of the fucntion with respect to that varible. By subbing in a value for x into you differentiated function you can find the rate of chage of f (dfdx) at that exact position.
