If the complex number z = 5 + 4i, work out 1/z.
1/(5 + 4i) * (5 - 4i)/(5 - 4i) = (5 - 4i)/41

I do not understand this topic and particularly this example. In the class the result was found out but I still do not get it. How did the teacher came up with this outcome?
Find the solution the the differential equation d^2y/dx^2 + (3/2)dy/dx + y = 22e^(-4x)
Solve the differential equations dx/dt=2x+y+1 and dy/dt=4x-y+1 given that when t=0 x=20 and y=60. (A2 Further pure)
