Q 1: Definite integral Which statements about a continuous function f : [a, b] -> R are correct? (A) If f = 0 then fo f(x)dx = 0. (B) If fo f(x) dx = 0 then f = 0. C) If fo f(x) dx = f" f(x)dx then f = 0. (D) Statements (A) and (C) are both true.Q 3: Another antiderivative Which statements about the sine and cosine functions sin : R > R and cos : R > R are correct? (A) sin is the only antiderivative of cos. (B) sin is the only antiderivative of cos whose graph goes through (0, 0). (C) There are infinitely many antiderivatives of cos whose graphs go through (0, 0). (D) None of these statements is true
