Math Problem Statement
Y=x^sinx, find dy/dx
Solution
To differentiate , we can use logarithmic differentiation. Here's the process:
-
Take the natural logarithm of both sides to make the exponent easier to handle: Using the property of logarithms , this becomes:
-
Differentiate both sides with respect to (using implicit differentiation on the left and the product rule on the right):
-
Solve for by multiplying both sides by :
-
Substitute back :
Thus, the derivative of is:
