I simulated this circuit on LTSpice.
From the calculations I get this transfer function:
Vo(s)/Vi(s) = 1/( sCR+(Rload+R)/Rload ) = 1/( 1/10000*s+6/5 ) (by choosing Rload = 5h, R = 1k, C = 100nF)
In the simulation I gave as input a step function to find the final value (Which turns out to be the same as I calculated).
1) If I want to plot the bode diagram, do I have to put a sine wave in the input or a step function also okay?
By maintaining a step function, I get:

The problem is that on wolframalpha I get:

I am probably doing something wrong on LTSpice ... I attach the file for your suggestion.
