**Differentiation**

**Chain rule:**

- You can use the chain rule to differentiate the function of a function
**If y = [F(x)]^n**then**Dy/Dx = n[F(x)]^n-1F'(x)****If y = F[g(x)]**then**Dy/Dx = F'[g(x)]g'(x)**- Example: If Y=(3x^4+x)^5 then Dy/Dx = 5(3x^4+x)^4(12x^3+1)

**Product Rule:**

- You can use the product rule when two functions u(x) and v(x…
