Suppose C is the curve r(t) = (6t,3to), for Osts 2, and F = (9x,3y) . Evaluate F . T ds using the following steps. C a. Convert the line integral | F . T ds to an ordinary integral. C b. Evaluate the integral in part (a). . . . a. Convert the line integral F . T ds to an ordinary integral. 2 F . T ds = dt (Simplify your answers.) The value of the line integral of F over C is (Type an exact answer, using radicals as needed.)
