Ok i solved the 2nd one and i think i will even solve the 3rd one its now only the 1st equation i have no ideas on
My maths are a bit rusty, if i can travel back in time and go back to school this would have been easy peasy
a= (2.P0.P1.P2-P2^2(P0+P2))/(P0.P2-P1^2)
Make the following the subject:
P0 then:
P1,
P2
AND:
B = ln((a/Po)-1)
Make Po the subject
AND:
y = T/N .ln(Po.(a-P1)/P1.(a-Po))
Make the following the subject
Po
P1
Any help will be apreciated
