Write a generic VBA Sub procedure to compute the value of the following Integral (I) using the Trapezoidal Rule. dac Solution // Trapazoidal rule calculates area under the curve // n is number of interval Function Integration(a As Integer, b as Integer, n As Integer) As Double Dim sum as Double sum = (F(a) + F(b))/2 For i = 1 To n - 1 sum = sum + F(a + ((b-a)/n)*i) Next i Integration = sum * (b-a)/n End Function.
