Understanding the Second Fundamental Theorem of Calculus

The video tutorial explains how to find the derivative of a function defined as a definite integral using the second fundamental theorem of calculus. The instructor introduces the problem of finding g prime of 27, takes the derivative of both sides of the equation, and applies the theorem to solve the problem. The tutorial emphasizes the usefulness of the theorem in simplifying complex integrals and concludes by calculating the cube root of 27 to find the solution.

What is the function g(x) defined as in the problem?

• A definite integral from 19 to x of the square root of t

• A definite integral from 19 to x of the cube root of t

• A definite integral from 0 to x of the cube root of t

• A definite integral from x to 19 of the square root of t

What is the role of the variable t in the integral defining g(x)?

• It is a constant

• It is the variable of integration

• It is the lower limit of integration

• It is the upper limit of integration

What condition must be met for the Second Fundamental Theorem of Calculus to apply?

• The function must be differentiable

• The function must be continuous on the interval
