Hey guys im completely new to this site and electronics so forgive me. Ive uploaded a photo of the question. Im trying to work out at what values does

just D1 conduct

D1 and D2 conduct

then finally all of them.

Im really stuck here. i know that the diodes start conducting when the voltage across them is equal to .7 volts.

i know that for only d1 conducting

Vout = 5/6 Vin

but i cant work out at what voltage does d2 being conducting. i know it has something to do with the voltage across the 5k resistor but im not sure how to maniuplate it.

any advice or help would be so very grateful..

thanks
