So, I tried so solve the first equation, where I am looking for $p_2$, in Mathematica with next command:
but i got
The function p2 appears with no arguments. I also before that defined:
p0:=(1+64*(1-z))^0.5 p1:=8*(1/p0-1) p0der:=z derivative(p0) !this is not code, just command p1der:=z derivative(p1) !this is not code, just command
What should i do to solve first $p_2$, after that $p_3$ symbolic in Mathematica, i am beginner I have no idea what could be mistake and how big is it?
