Math Problem Statement

Differentiate the function. g(t) = ln(6 + t8)

Solution

To differentiate the function g(t)=ln(6+t8)g(t) = \ln(6 + t^8), we will use the chain rule.

Steps:

  1. Differentiate the outer function: The derivative of ln(x)\ln(x) with respect to xx is 1x\frac{1}{x}. So, for g(t)=ln(6+t8)g(t) = \ln(6 + t^8), treat 6+t86 + t^8 as the inner function. ddt(ln(6+t8))=16+t8ddt(6+t8)\frac{d}{dt} \left( \ln(6 + t^8) \right) = \frac{1}{6 + t^8} \cdot \frac{d}{dt}(6 + t^8)

  2. Differentiate the inner function: The derivative of 6+t86 + t^8 with respect to tt is 8t78t^7 (since 66 is constant, its derivative is 0). ddt(6+t8)=8t7\frac{d}{dt}(6 + t^8) = 8t^7

  3. Combine the results: Multiply the derivatives of the outer and inner functions. g(t)=16+t88t7=8t76+t8g'(t) = \frac{1}{6 + t^8} \cdot 8t^7 = \frac{8t^7}{6 + t^8}

Thus, the derivative of g(t)=ln(6+t8)g(t) = \ln(6 + t^8) is: g(t)=8t76+t8g'(t) = \frac{8t^7}{6 + t^8}

Here are 5 related questions to explore:

  1. What is the derivative of g(t)=ln(t8+t2)g(t) = \ln(t^8 + t^2)?
  2. How do you apply the chain rule in general cases of logarithmic functions?
  3. What happens to the derivative as t0t \to 0 or tt \to \infty in the function g(t)g(t)?
  4. How would you find the second derivative of g(t)=ln(6+t8)g(t) = \ln(6 + t^8)?
  5. What is the derivative of g(t)=ln(a+tn)g(t) = \ln(a + t^n) where aa and nn are constants?

Tip: When differentiating composite functions like ln(f(t))\ln(f(t)), always apply the chain rule by differentiating the outer and inner functions separately.
