Two Fundamental Theorems about the Definite Integral

WebExpert Answer. 1st step. All steps. Final answer. Step 1/4. To solve the given problem, we need to understand the Concept and meaning of Definite Integral. Let g ( x) be an integrable function on an interval [ a, b]. The definite integral of g ( x) from x = a → x = b is the Net Signed Area under the graph of g ( x) . . WebNow, let us compute its derivative. d/dx∫ a b f(x) dx = d/dx [F(b) - F(a)] = 0 (as F(b) and F(a) are constants). Thus, when both limits are constants, the derivative of a definite integral is 0. i.e., d/dx ∫ a b f(t) dt = 0. When One of the Limits is a Constant.
