# Math Help - Small Increments 1

1. ## Small Increments 1

Bernoulii's equation from fluid mechanics may be written as H = p + (Pv^2)/2 where p is the pressure P is the constant density of the fluid, v is the velocity and H is a constant.
Obtain an approximate formula for the change in pressure §p due to the small change in velocity §v.

Chain rules for this question is ??

Thank

2. I stuck at chain rules in this question.
