# First order differential equation help

I have a problem solving a first order differential equation:

dT/dP - C2/T = C1 Where C2 and C1 are just constants, the differential equations book I have does not address the situation of 1/T. I am trying to develop my own integrating factor but it would be nice for a little guidance.

$$\frac{1}{T}=T^{-1}$$

You can then express the above as:

$$\frac{dT}{dP} - C_{1} \ = C_{2}T^{-1}$$

which would then be in the form of a Bernoulli differential equation.

I need to learn how to use the little equation editor that everyone else uses it makes equations way easier to read.

The equation editor I use here is in-built into the forums. It's called LaTeX. You can learn to use it rather easily. Click on the equations and download the latex reference PDF files. If you want to learn how to input a particular maths expression you see, just click on it to see how it's done.
