The correct formula for finding the derivative of the product of two functions is d/dx(a.b) = a'(x) * b(x) + a(x) * b'(x)
The formula for finding the derivative of the product of two functions
From the question, we have the following parameters that can be used in our computation:
The product of two functions
Let two functions be represented as
a(x) and b(x)
Such that
f(x) = a(x) * b(x)
The product rule states that
if f(x) = a(x) * b(x)
Then
d/dx(a.b) = a'(x) * b(x) + a(x) * b'(x)
Hence, the formula is d/dx(a.b) = a'(x) * b(x) + a(x) * b'(x)
