The Second Fundamental Theorem states that if f(x) is a continuous function on an interval [a, b], then the definite integral of f(x) from a to b is equal to the difference between the antiderivative of f(x) evaluated at b and the antiderivative of f(x) evaluated at a.

First Fundamental Theorem of Calculus

The First Fundamental Theorem of Calculus is a fundamental concept in calculus that establishes a connection between integration and differentiation. It relates the concept of finding the area under a curve to finding the antiderivative of a function. The theorem is based on the fundamental notion of the limit and is one of the most important theorems in calculus. The theorem states that if f(x) is a continuous function on an interval [a, b], then the definite integral of f(x) from a to x is differentiable on the interval (a, b), and its derivative is f(x) evaluated at x. In other words, the derivative of the definite integral of f(x) from a to x with respect to x is equal to f(x).

Mathematically, the First Fundamental Theorem of Calculus can be stated as follows:

If f(x) is a continuous function on [a, b], then the function g(x) defined by g(x) = ?a^x f(t) dt is differentiable on (a, b), and g'(x) = f(x) for all x in (a, b). This theorem has a significant impact on the development of calculus, as it provides a powerful tool for solving problems that involve finding the area under a curve. The theorem enables us to calculate the derivative of the definite integral of a function, which in turn allows us to find the slope of a tangent line to a curve at any point. The First Fundamental Theorem of Calculus is often used in applications where we need to calculate the area under a curve. For example, it can be used to calculate the total distance traveled by an object whose velocity is given by a function. The definite integral of the velocity function over a given time interval gives the total displacement of the object over that interval, while the derivative of the definite integral gives the instantaneous velocity at any point in time. Another application of the theorem is in economics, where it is used to calculate the present value of future cash flows. The theorem allows us to calculate the integral of the cash flows over a given period, and the derivative of the integral gives the present value of the cash flows at any point in time. The proof of the First Fundamental Theorem of Calculus is based on the definition of the definite integral as a limit of Riemann sums. It involves showing that as the number of subintervals in the Riemann sum increases, the sum approaches the definite integral of the function. By using the limit definition of the derivative, we can then show that the derivative of the definite integral is equal to the function itself. In summary, the First Fundamental Theorem of Calculus is a powerful tool in calculus that establishes a connection between integration and differentiation. It allows us to calculate the derivative of the definite integral of a function, which in turn enables us to find the slope of a tangent line to a curve at any point. The theorem has many applications in science, engineering, economics, and other fields, making it one of the most important concepts in calculus.
