An approximation to the integral of a function f(x) over an interval [a, b] can be found by first approximating f(x) by the straight line that goes through the end points (a, f(a)) and (b, f(b)), and then finding the area under the straight line, which is the area of the trapezoid. The resulting formula becomes:
lim(a→b) ∫ f(x)d(x) = (b-a)/2[f(a) + f(b)]
Write a function trapezint1( f, a,b) that returns this approximation to the integral. The argument f is a Python implementation f(x) of the mathematical function f(c). For instance, the result of trapezint1( math. sin,0,0.5* math. pi ) should be 0.7854 (with some numerical error). The result of trapezint1( abs, -1,1 ) should be 2.0.

Johnson enterprises uses a computer to handle its sales invoices. lately, business has been so good that it takes an extra 3 hours per night, plus every third saturday, to keep up with the volume of sales invoices. management is considering updating its computer with a faster model that would eliminate all of the overtime processing.
