This probably calculate the bonus damage for each attack. Example if skill is fire and the player has Fire Attribute this probably does some check and return a number. 1 Is the default which mean no bonus.

The

if (diff > 0...

return something between 1.025 (+a square) and 1.25 which mean it multiply the attack dmg by that number

Let's say the dmg is 700 and it multiply by 1.025 which has a result of 717.25. Or if you multiply 700 with 1.25 has a result of 875

so  this is correct ?

   return Math.min(1.075 + (Math.sqrt(Math.pow(diff, 3) / 2) * 0.0001), 1.75);

I don't know from which aspect you ask if is correct. As values? I dont know, as coding yes it's fine. You might no see difference because the damage addon is way too low. In 350 it add barely 5-50 bonus damage +/-

 

Do the maths. Ex. 350 Dmg * 1.075 and see the bonus.
