Let f (ac) = Vac + a for1

Let f @) = V/ 2 7 1 + c forl 7 . We wish to estimate by the Trapezoidal Rule. a) Divide the domain of f into 4 sub-intervals of equal length. Calculate their common length (exact value). b) Find the approximation of 7 1 that the Trapezoidal Rule produces with 4 sub-intervals. Give the answer with 0.0001 precision. Number
