Question 3: Given the following function F(x), calculate its derivative. Question 2: Given the following function F(x), calculate its derivative. This can be solved using the fundamental theorem of calculus part – I Question 1: Given the following function F(x), calculate its derivative. Let’s look at some problems related to these concepts. To solve such problems, we need a more generalized version of the fundamental theorem.įor a function f which is continuous and two other functions g and h which are differentiable, Hard problems of definite integrals can be solved by combining the chain rule and the fundamental theorem of calculus. Then,Īpplying Fundamental Theorem with Chain Rule This is the second part of the Fundamental Theorem of Calculus.įundamental Theorem of Calculus – Part IIįor a function f which is continuous and differentiable on the interval, let F be any anti-derivative of the given function. This theorem can be used to derive a popular result, There is a function f(x) = x 2 + sin(x),Īccording to the fundamental theorem mentioned above, This theorem seems trivial but has very far-reaching implications.
Then, F is a differentiable function on (a, b), and The fundamental theorem enables us to calculate the derivatives of the given function.įor a function f which is continuous and differentiable on the interval, suppose. Now geometrically, this function gives us the area under the same curve but from x = a to x, where x lies between the boundaries of the limits. This definite integral can be converted into a function by varying the upper bound of the limit. This is defined as the area enclosed by the function f(x) and x-axis between the limits x = a and x = b. The definite integral between these limits is denoted by.

#FUNDAMENTAL THEOREM OF CALCULUS PART 2 HOW TO#
It is possible to evaluate definite integrals of some discontinuous functions Not tell us how to find an antiderivative of, and it does not tell us how to find the definite integral of aĭiscontinuous function. The definite integral of a continuous function can be found by finding an antiderivative of (anyĪntiderivative of will work) and then doing some arithmetic with this antiderivative. Then for all so and, the formula we wanted. Proof: If is an antiderivative of, then are both antiderivatives of, , so and differ by a constant: for all. If is continuous and is any antiderivative of , The Fundamental Theorem of Calculus (Part 2)
If we know and can evaluate some antiderivative of a function, then we can evaluate any definite integral of
