Formulas For Differential Co-officiant

**Before find differential co-officiant of any mathematical term it is important to remember these formulas . These formulas are very helpful to find differential co-officiant .**

**1) *** (d/dx)(c)=0*
** where *** c* is a constant

**2) *** (d/dx)(u+v)=(du/dx)+(dv/dx)*

**3) *** (d/dx)(u-v)=(du/dx)-(dv/dx)*

**4) *** (d/dx)(u.v)=(vdu/dx)+(udv/dx)*

**5) *** (d/dx)(u/v)=[(vdu/dx)+(udv/dx)]/v.v*

**6) *** (d/dx)(cu)=cdu/dx*

** where *** c* is a constant .

**7) *** dy/dx=(dy/du)(du/dx)*

**8) *** dy/dx=1/(dx/dy)*

**9) *** dy/dx= (dy/du)(du/dv)(dv/dx) *
