Product rule for two derivatives

Click For Summary
SUMMARY

The discussion centers on the application of the product rule in calculus when taking two derivatives. The product rule for the first derivative is established as u'v + uv'. To find the second derivative, one must apply the product rule again to each term of the first derivative, treating the resulting expressions as products. This method involves using both the product and chain rules as necessary to differentiate each term accurately.

PREREQUISITES
  • Understanding of basic calculus concepts, specifically derivatives.
  • Familiarity with the product rule for differentiation.
  • Knowledge of the chain rule in calculus.
  • Ability to manipulate algebraic expressions involving functions.
NEXT STEPS
  • Study the application of the product rule in higher-order derivatives.
  • Learn about the chain rule and its interaction with the product rule.
  • Practice differentiating complex functions using both product and chain rules.
  • Explore examples of second derivatives in calculus textbooks or online resources.
USEFUL FOR

Students of calculus, mathematics educators, and anyone seeking to deepen their understanding of differentiation techniques in calculus.

Homework Statement




I was just wondering if there is a formula for the product rule when you take two derivatives ... ?

Homework Equations



I know the product rule for one derivative .. is u'v + uv' !



The Attempt at a Solution



I just want a formula without a proof

If I'm understanding what you're asking, you want the derivative of the resultant of the product rule. The way to do it is just to treat them as you did with the first derivative.

You know that uv = u'v +uv'

Well that is basically the same as taking the derivative of ab + cd so you have to apply the product rule again to each term.
 
You mean to find the second derivative after you've used the product rule to find the first derivative?

Just differentiate each term using Product/chain rules as necessary.
