Use logarithmic differentiation to find the derivative of the function. y = x7 cos(x) Step 1 Using properties of logarithms, we can rewrite the equation as In(y) = In(x7 cos(x)), which is equivalent to Inty) = ( 7 cos (x) 7 cos(x) dn(x)). Step 2 Note that 7 cos(x) In(x) is a product. Therefore, its derivative is given by (7 cos(x)) In(x) + (In(x))( 7 cos(x) Submit Skip (you cannot come back)
