Math Problem Statement

Find f’(x). f(x)=sin(e^2x)

Solution

To find f(x)f'(x) for the function f(x)=sin(e2x)f(x) = \sin(e^{2x}), we will use the chain rule.

The chain rule states: ddx[sin(g(x))]=cos(g(x))g(x)\frac{d}{dx} [\sin(g(x))] = \cos(g(x)) \cdot g'(x)

Here, g(x)=e2xg(x) = e^{2x}, so we need to find the derivative of e2xe^{2x} first: ddx[e2x]=2e2x\frac{d}{dx} [e^{2x}] = 2e^{2x}

Now, applying the chain rule: f(x)=cos(e2x)2e2xf'(x) = \cos(e^{2x}) \cdot 2e^{2x}

Thus, the derivative of f(x)=sin(e2x)f(x) = \sin(e^{2x}) is: f(x)=2e2xcos(e2x)f'(x) = 2e^{2x} \cos(e^{2x})

Let me know if you have any questions! Here are 5 related questions to further your understanding:

  1. What is the derivative of f(x)=cos(e2x)f(x) = \cos(e^{2x})?
  2. How would the derivative change if f(x)=sin(e3x)f(x) = \sin(e^{3x})?
  3. Can you find the second derivative f(x)f''(x) for f(x)=sin(e2x)f(x) = \sin(e^{2x})?
  4. What is the general rule for differentiating composite functions?
  5. How would you differentiate f(x)=sin(e2x2)f(x) = \sin(e^{2x^2})?

Tip: When applying the chain rule, always start by identifying the outermost function and work inward.
