20. Using the general property d dx exp( bx )= b exp( bx ), we write v = dx dt = µ d (19 t ) dt · e t +(19 t ) · µ de t dt . If a concern develops about the appearance of an argument of the exponential ( t ) apparently having units, then an explicit factor of 1 /T where T = 1 second can be inserted and carried through the computation (which does not change our answer). The result of this diFerentiation is
