Solve the differential equation and show that the solution can be expressed in the form
m=50 - 500/(t+10)
2.By first expressing 1/a(10-a) as partial fractions , solve the differential equation , obtaining an expression for t in terms of a.
I got the partial fraction 1/10a + 1/10(10-a)
but i don`t have any idea what to do next.. any help ?
