I have both bad news and good news for you.
bad news is-your theorem has already exist. in differential equation field, there is a similar formula called Euler's Method to evaluate f(x+a), given f'(x+t) 0<t<a and f(x).
Still Congratulations! You have your Own Thought and Creativity.
Keep this thinking habit and Eventually you'll break a point in some field!
