What is the Fundamental Theorem of Calculus?

Back

The Fundamental Theorem of Calculus links the concept of differentiation and integration, stating that if a function is continuous on [a, b], then the integral of its derivative over that interval equals the difference in the values of the function at the endpoints: ∫_a^b f'(x) dx = f(b) - f(a).

What is the relationship between differentiation and integration?

Back

Differentiation is the process of finding the rate at which a function is changing at any given point, while integration is the process of finding the total accumulation of a quantity. The Fundamental Theorem of Calculus shows that these two processes are inverses of each other.

How do you find the area under a curve using integration?

Back

To find the area under a curve defined by a function f(x) from x = a to x = b, you compute the definite integral: Area = ∫_a^b f(x) dx.

What is a definite integral?

Back

A definite integral is an integral that has specified upper and lower limits, representing the net area under the curve of a function between those two points.

Front

What is an indefinite integral?

Back

An indefinite integral represents a family of functions and is expressed without limits. It is the antiderivative of a function, denoted as ∫f(x) dx = F(x) + C, where C is the constant of integration.

What is the power rule for integration?

Back

The power rule for integration states that ∫x^n dx = (x^(n+1))/(n+1) + C, for n ≠ -1.

What is the area under the curve of f(x) = 5x^4 + 3x + 7 from x = 0 to x = 4?

Back

To find the area, compute the definite integral: ∫_0^4 (5x^4 + 3x + 7) dx = 1076.

What is the significance of the constant of integration?

Back

The constant of integration (C) represents the family of all antiderivatives of a function, indicating that there are infinitely many functions that differ by a constant.

Front

What is the geometric interpretation of the definite integral?

Back

The definite integral can be interpreted as the net area between the curve of the function and the x-axis over the specified interval.

What is the Fundamental Theorem of Calculus Part 1?

Back

Part 1 states that if f is continuous on [a, b], then the function F defined by F(x) = ∫_a^x f(t) dt is continuous on [a, b], differentiable on (a, b), and F'(x) = f(x).
