SUMMARY

The discussion focuses on differentiating the function V(x) = 300x * sqrt(1296 - x^2) using both the product and chain rules. The user initially struggled with the product rule alone but was advised to incorporate the chain rule for the square root function. The correct approach involves applying the product rule to the entire expression while also differentiating the inner function g(x) = 1296 - x^2 using the chain rule.

PREREQUISITES
  • Understanding of the product rule in differentiation
  • Knowledge of the chain rule in differentiation
  • Familiarity with square root functions and their derivatives
  • Basic algebraic manipulation skills
NEXT STEPS
  • Practice differentiating functions using both the product and chain rules
  • Study examples of differentiating composite functions
  • Learn about higher-order derivatives and their applications
  • Explore the implications of differentiation in real-world scenarios
USEFUL FOR

Students studying calculus, mathematics educators, and anyone looking to improve their skills in differentiation techniques.

Differentiating an equation!

Homework Statement


How do I differentiate this

V(x) = 300x * sqrt(1296-x^2)



The Attempt at a Solution



I tried using the product rule but that didnt work at all


PLease help

Thank you so much!

Hint f(x)=\sqrt{g(x)}
Then:
<br /> f&#039;(x)=\frac{g&#039;(x)}{2\sqrt{g(x)}}<br /> [
Now use the product rule
 


To elaborate on what hunt_mat said, you do have to use the product rule, but you also need to use the chain rule.
