Step by step on how to solve this

Step by step on how to solve h(x) = sin(ln(x^5))

Solution

To solve for the derivative of h(x)=sin(ln(x5))h(x) = \sin(\ln(x^5)), we'll proceed with the following steps:

Step 1: Rewrite the Function

The function is given by: h(x)=sin(ln(x5))h(x) = \sin(\ln(x^5)) Using the logarithmic identity ln(x5)=5ln(x)\ln(x^5) = 5 \ln(x), we can rewrite h(x)h(x) as: h(x)=sin(5ln(x))h(x) = \sin(5 \ln(x))

Step 2: Differentiate h(x)h(x) with Respect to xx

We want to find h(x)h'(x), the derivative of h(x)h(x).

This requires applying the chain rule. Let: u=5ln(x)u = 5 \ln(x) so that h(x)=sin(u)h(x) = \sin(u). The derivative h(x)h'(x) then becomes: h(x)=cos(u)uh'(x) = \cos(u) \cdot u'

Step 3: Find uu' with Respect to xx

Since u=5ln(x)u = 5 \ln(x), we find uu' by differentiating 5ln(x)5 \ln(x) with respect to xx: u=51x=5xu' = 5 \cdot \frac{1}{x} = \frac{5}{x}

Step 4: Substitute uu and uu' Back into h(x)h'(x)

Now, we can substitute u=5ln(x)u = 5 \ln(x) and u=5xu' = \frac{5}{x} into the derivative formula: h(x)=cos(5ln(x))5xh'(x) = \cos(5 \ln(x)) \cdot \frac{5}{x}

Final Answer

Thus, the derivative h(x)h'(x) is: h(x)=5cos(5ln(x))xh'(x) = \frac{5 \cos(5 \ln(x))}{x}

Here are some related questions to expand your understanding:

  1. How would the derivative change if the function was h(x)=sin(ln(xn))h(x) = \sin(\ln(x^n)) with any exponent nn?
  2. What if we replaced sin\sin with another trigonometric function, like cos\cos?
  3. How does the chain rule apply to composite functions like this one?
  4. What other identities could be useful for simplifying functions with logarithmic and exponential expressions?
  5. How would you integrate a function similar to h(x)h(x) instead of differentiating it?

Tip: When working with logarithmic and trigonometric functions together, simplify expressions using logarithmic properties first before applying derivatives.
