In this video I show that the derivative of a vector function is equal to the derivative of the real-valued functions in its components. I prove this by applying the definition of derivatives for vector functions, and then apply basic limit and vector laws to obtain the corresponding definition of derivative of each real-valued function in each component. This is a straight forward proof, and the result means that to obtain the derivative of a vector function, we just take the derivative of it components!
