J. 40, No. 5, 373-374 (2009).} \itemab Summary: The Taylor polynomial is used to approximate a real function in the neighborhood of a point. Here we give a short straightforward proof for the bound of the remainder term of this approximation. The proof uses only induction and the fact that non-negativity of the derivative implies monotonicity of the function, thus it is suitable for presentation to undergraduates.
