How to Evaluate the Derivative of a Logarithmic Function with a Base of 10?

Click For Summary
SUMMARY

The discussion focuses on evaluating the derivative of the function g(t) = (10^t)(log t) at t = 10. Participants emphasize the importance of using the product rule for differentiation rather than taking the logarithm of both sides. The derivative is calculated using the formula \(\frac{d}{dx}a^x = a^x \log a\), which is crucial for functions involving exponential and logarithmic components.

PREREQUISITES
  • Understanding of differentiation rules, particularly the Product Rule.
  • Familiarity with exponential functions, specifically the form a^x.
  • Knowledge of logarithmic functions, particularly log base 10.
  • Basic calculus concepts, including limits and derivatives.
NEXT STEPS
  • Study the Product Rule in calculus for differentiating products of functions.
  • Learn about the properties of logarithms, especially log base 10.
  • Explore the application of the chain rule in differentiation.
  • Practice evaluating derivatives of exponential functions with various bases.
USEFUL FOR

Students studying calculus, particularly those learning about derivatives of logarithmic and exponential functions, as well as educators looking for examples to illustrate these concepts.

Homework Statement


if g(t)=(10^t)(log...t) then evaluate g'(10)
......10 <---------(my attempt at a log base 10)

Homework Equations



im completely lost...i don't know if i should take the ln of both sides...or what to do really.

The Attempt at a Solution

[tex]g(t)=10^t\log t[/tex]

Naw don't take log of both sides, just differentiate from the get go :)

[tex]\frac{d}{dx}a^x=a^x\log a[/tex]

Don't forget the Product rule.
