Re: differentiation of fractional and negative powers

Click For Summary
SUMMARY

The discussion centers on differentiating the function \( \frac{1}{\sqrt{3x^2 + 2}} \) using the limit definition of the derivative, specifically the formula \( \frac{f(x+\delta) - f(x)}{\delta} \). Participants emphasize the importance of attempting the problem independently before seeking assistance. They recommend consulting textbook examples related to square-root functions to gain a better understanding of the differentiation process.

PREREQUISITES
  • Understanding of basic calculus concepts, particularly differentiation.
  • Familiarity with the limit definition of a derivative.
  • Knowledge of square-root functions and their properties.
  • Ability to manipulate algebraic expressions involving radicals.
NEXT STEPS
  • Study the limit definition of a derivative in detail.
  • Practice differentiating square-root functions using various methods.
  • Review examples of differentiating composite functions.
  • Explore the application of the chain rule in differentiation.
USEFUL FOR

Students studying calculus, particularly those struggling with differentiation techniques, and educators seeking to guide students through complex derivative problems involving square-root functions.

Hi !
Im having a problem with a question!

I need to differentiate the equation 1/ root of (3x^2 + 2) !
Using the formula (f(x+delta) - f(x)) / delta !
Your help would be appreciated!

Thanks for posting in the correct forum :smile:

Yes, those square-root problems are tricky at first.

We do need to see an attempt (by you) at solving the problem before we offer help. Your textbook probably has an example worked out, involving a square-root function. Look at that, see what you can come up with, and then post here again.
