Looks like a quotient rule proof, the first line is just similar triangle ratios. Not sure about the differential part on the triangle though, d g/a/b isn't a constant

Is this infinitesimal calculus? Never studied it before but this makes sense to me.
The first and second lines follow from similiar triangles if thats what your confused about.

to help brainlets the first line should be written as gamma/1 = a/b

thanks, I was wondering how tf y = a/b

whats the reasoning behind eliminating (b)(db) from b^2 + (b)(db) from the denominator?

b*(db) is infinitesimally small. Hence it has no effect on the larger term b^2

It’s just geometry, and the proof is bad anyway, skills a few steps and makes it less clear by not adding a /1 where it’s due

lm fucking ao

who the fuck memorizes or cares about the quotient rule? just use the product rule , its faster 100% of the time anyway and you can derive the quotient rule from it

further proof that using d was fucking stupid and Leibniz made terrible notation.
