Math Problem Statement

derivative of y=e^sin2x

Solution

To find the derivative of y=esin(2x)y = e^{\sin(2x)}, we'll use the chain rule.

Steps:

  1. Outer Function: The outer function is eue^u, where u=sin(2x)u = \sin(2x). The derivative of eue^u with respect to uu is simply eue^u.

    So, ddueu=eu\frac{d}{du} e^u = e^u.

  2. Inner Function: The inner function is sin(2x)\sin(2x). We need to differentiate this with respect to xx.

    The derivative of sin(2x)\sin(2x) with respect to xx is 2cos(2x)2\cos(2x), using the chain rule.

Thus, applying the chain rule:

dydx=esin(2x)2cos(2x)\frac{dy}{dx} = e^{\sin(2x)} \cdot 2\cos(2x)

Final Answer:

dydx=2cos(2x)esin(2x)\frac{dy}{dx} = 2\cos(2x) \cdot e^{\sin(2x)}

Let me know if you'd like more details or have any further questions!

Here are some related questions to explore:

  1. How do we apply the chain rule in general?
  2. What is the derivative of y=ecos(2x)y = e^{\cos(2x)}?
  3. How does the derivative change if the exponent is different, like esin(3x)e^{\sin(3x)}?
  4. How do you find the derivative of composite functions that involve trigonometric functions?
  5. Can the chain rule be used for higher-order derivatives?

Tip: Always carefully identify the "inner" and "outer" functions when using the chain rule!
