Find the Derivative - d/dx y=e^(cos(x))

Problem

d()/d(x)*ecos(x)

Solution

1. Identify the outer function and the inner function to apply the Chain Rule. The outer function is eu and the inner function is u=cos(x)

2. Apply the Chain Rule, which states that the derivative of eƒ(x) is eƒ(x)⋅d(ƒ(x))/d(x)

3. Differentiate the inner function cos(x) with respect to x which results in −sin(x)

4. Multiply the derivative of the outer function by the derivative of the inner function to find the final result.

Final Answer

d(ecos(x))/d(x)=−sin(x)*ecos(x)
