Mastering The Product Rule Of Differentiation: How To Easily Derive Constant Multiplication In Math

d/dx (k×f)=

k×f’

To take the derivative of a product of a constant k and a function f with respect to x, we use the product rule of differentiation which states:

d/dx (k×f) = k×d/dx (f) + f×d/dx (k)

Since k is a constant, its derivative with respect to x is zero. Therefore, the above equation simplifies to:

d/dx (k×f) = k×d/dx (f)

So, the derivative of k times f with respect to x is k times the derivative of f with respect to x.
