These lessons will involve the students in investigating and understanding:
That anti-differentiation is the reverse process of differentiation.
How to find the anti-derivative F(x) of function ݂f(x)
That the indefinite anti-derivative is the set of all possible antiderivatives of a function
That a distinct anti-derivative is one element of this set which satisfies some initial condition
That the process of finding the area between a curve and the x -axis (or y– axis) over an interval on the axis, is known as integration
That the area between a function and the x-axis over an interval may be calculated using the limit of the sum of the areas of rectangles, as the number of rectangles tends to infinity and the width of each rectangle tends to zero.
That the area A between the graph of ݂f(x) and the x-axis over the interval from [a,b] is :
The area beneath a function f(x) from a to b is given by:
The antiderivative is usually called the indefinite integral
The indefinite integral, of ݂f(x) is a set of functions equal to the set of all the antiderivatives of f(x). They differ by a constant C.
The definite integral with limits a to b is a number equal to the net signed area between the graph of ݂f(x) and the interval [a,b]
