Attachment 29066 Could someone work out how the third equation (43) becomes the fourth equation (44). Seems like magic to me. Where does the K on the Tsub0 term go?

Just integrate the 3rd equation carefully, you will see (Wink)

it's pretty clear that is what I am having trouble with

lol. When you integrate the 1st term on the RHS, integral of is which cancels out the k in the numerator. The integral of the LHS is itself. The constant c is a constant of integration. First just integrate on both sides and divide both sides by . You will arrive at the answer. Hope this helps.
