geometric interpretation. Imagine that the area under f (Fig. a) is a liquid that can "leak" through the graph to form a rectangle with the same area (Fig. b). If the height of the rectangle is H, then the area of the rectangle is H ab . We know the area of the rectangle is the same as the area under f so ³ ³b b a H b a f x dx. Then a f x dx

8.1 Introduction. The ability to calculate the area under a graph is one of the most important discoveries of integral Calculus. Prior to Calculus, area was computed by dividing a zone into very small strips and summing the individual areas. The accuracy of the result is improved simply by making the strips smaller and smaller, taking the ...

The trapezoidal rule is a numerical integration method to be used to approximate the integral or the area under a curve. The integration of [a, b] from a functional form is divided into n equal pieces, called a trapezoid. Each subinterval is approximated by the integrand of a constant value. This paper provides three SAS macros to perform the ...

This is the area under the bell curve shown in Figure 1. The trick is to compute V in a different way — by slices. Amazingly, we’ll discover that V = Q2, which will tell us the value of Q: Q2 = V Q2 = π Q = √ π. So now we need to check that V = Q2. area F(x) x Figure 2: F (x) = 0 x e−t2dt dt.

Think of a as fixed and b as varying. Then the area under y = f(x) from a to b is a function of b: A(b) = the area under the graph of f between a and b, A(x) = the area under the graph of f between a and x. One thing to be said about this function is that A(a) = 0: The area between a and a is 0. Math 10A Antiderivatives and area

3. Euler’s method can be used to approximate solutions of differential equations when finding an explicit solution is too difficult or impossible. This method is based on making a series of “corrections” to the tangent line approximation. (a) The general formula for Euler’s method is yn = yn−1 + hF (xn−1, yn−1).
