Remaining Time: 278:41:50 b The following expression represents the integral/ f(x) dax for some real number a and b, and a function f. 3 3i lim -sin ( 3+ a) Find A: and a; in this expression and deduce the values of a and b, and the function f. The Ax term should be an expression involving n, ; should be an expression involving the index i and n, a and b are real numbers, and f(x) should be an expression involving a. Don't forget to include square brackets; use calculator notation (e.g. 3x- is written 3 * a*2); and list your answers separated by commas. Answer: [Ax, a; , a, b, f(x)] - b) Compute the value of the limit above. Give your answer to four decimal places. 3 Answer: lim -sin Number 1-+00
