You are not given any value  ?
or do you just need to derive it according to each term?

are you given another equation because with the two capital T's there I can't see a way of isolating T.

I got T= -kth/2
But i'm a bit brain dead after not looking at maths for 3 months after Uni... So i expect it is wrong

I haven't had a math class in a year and a half, but I think you need to use the number 'e' somehow to resolve lin, but I'm far from certain. I could solve it very easily with my calculator, but I guess you need the calculations in-between aswell.

I think you probably need that as well, could you give it to us?

Ok, I have solved it:
T=(W(h*e^-tk-bh)+bh)/h
where W is the product log or Lambert function.

I got a computer to solve this so it should be correct.

yeah sorry I had to change it in the computer becuase it kept assuming I was an imaginary number.
