The Fundamental Theorem of Calculus (FTC) Section 4.4 – Part 2 The Fundamental Theorem of Calculus (FTC)
FTC Part 2 Definite Integral as a number To understand FTC part 2, we need to think of the integral as a function. Definite Integral as a number Definite Integral as a Function F is a function of x Constant f is a function of x f is a function of t Constant Constant
Ex: Evaluate the following function at
In the previous example, the derivative of F is the original integrand with only the variable changed. This brings us to FTC Part 2.
The second Fundamental Theorem of Calculus If f is continuous on an open interval containing a, then, for every x in the interval,
Ex: Evaluate
Ex: Find the derivative of
Notes Break! Work on the following problems from your book: p. 294 – 295 #66, 69 – 89 EOO
Distance VS Displacement Distance: total amount traveled Displacement: distance from starting point
**Remember: The derivative of the position function is the velocity function. The antiderivative of the velocity function is the position function.
Displacement: Distance:
