does anyone know how i should find vd1 and vd2 for this circuit

 

Measure the voltage drop across each (If I understand your question).

yes i know i should measure the voltage but i can't find any proper kcl/kvl equation to solve it using repear method. thank you though.

 

That's always been a problem for me too. The formula is:
(5.1)

But I have difficulty figuring IS for a given junction. Maybe somebody will happen along with that part of the solution. In the meantime, have a look at this:

Especially around the middle of the page.

 

YES, I know.

 

The two diodes are in series.
I think it may not be possible to derive a closed-form solution.

 

The voltage across each diode, assuming that they are normal silicon diodes with no special characteristics, will be 0.7 volts (One digit resolution) I do not interpret the voltage from the simulator notation so I will not guess at the current.

 

If one needs to be more precise in the calculation of the diodes, which will be a whole lot more complex because the currents will be a bit different. IN addition, as the voltage increases from zero, there will be changes in the equation as the diodes become biased into conduction.
So this is actually a rather nasty problem because of two dependent variables coming into play as the supply voltage changes.
