Q. Find the derivative of the following function.y=e−5x5Answer: y′=
Identify Function and Rule: Identify the function and the rule to use for differentiation.We have the function y=e−5x5. To find the derivative y′, we will use the chain rule, which states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function.
Apply Chain Rule: Apply the chain rule to differentiate the function.The outer function is eu where u=−5x5. The derivative of eu with respect to u is eu. The inner function is u=−5x5, and its derivative with respect to x is −5×5x5−1=−25x4.
Multiply Derivatives: Multiply the derivatives of the outer and inner functions.y′=e−5x5×(−25x4)
Simplify Expression: Simplify the expression if necessary.The expression is already simplified, so we have the final answer.y′=−25x4e−5x5
