# Could i be shown this integration by parts step by step

## Homework Statement

αh=α-ε+ih

ΔαH/Δα= dαH/dα = d/dα x (α-ε+ih) = 1-(dε/dα)

I don't see any integration. I see only differentiation.

What differentiation do you see? it would be great if you could write what you see so that i can see it as well.

He see's what you've written. I see it the same way.

H/dα = d/dα x (α-ε+ih) = 1-(dε/dα)
