Define Accumulation Function.

A function defined by a definite integral where one of the limits of integration is a variable.

What does the Fundamental Theorem of Calculus relate?

Differentiation and integration; it shows they are inverse processes.

What is the integrand?

The function inside the integral that is being integrated.

What is a definite integral?

An integral with upper and lower limits, resulting in a numerical value.

What is an antiderivative?

A function whose derivative is the original function.

What is the upper bound of an integral?

The upper limit of integration in a definite integral.

What is the lower bound of an integral?

The lower limit of integration in a definite integral.

Define the Chain Rule.

A rule for differentiating composite functions.

What is the derivative?

The instantaneous rate of change of a function with respect to its variable.

What is integration?

The process of finding the area under a curve.

How to find g(x)g'(x) if g(x)=axf(t)dtg(x) = \int_{a}^{x} f(t) dt?

Apply the Fundamental Theorem of Calculus: g(x)=f(x)g'(x) = f(x).

How to find g(x)g'(x) if g(x)=au(x)f(t)dtg(x) = \int_{a}^{u(x)} f(t) dt?

Apply the Fundamental Theorem of Calculus and the Chain Rule: g(x)=f(u(x))cdotu(x)g'(x) = f(u(x)) cdot u'(x).

How to find g(c)g'(c) given g(x)=axf(t)dtg(x) = \int_{a}^{x} f(t) dt?

First find g(x)g'(x) using the Fundamental Theorem of Calculus, then evaluate g(c)g'(c).

How to find F(x)F'(x) if F(x)=u(x)bf(t)dtF(x) = \int_{u(x)}^{b} f(t) dt?

First, switch the limits: F(x)=bu(x)f(t)dtF(x) = -\int_{b}^{u(x)} f(t) dt. Then, F(x)=f(u(x))cdotu(x)F'(x) = -f(u(x)) cdot u'(x).

How to find g(x)g'(x) if g(x)=u(x)v(x)f(t)dtg(x) = \int_{u(x)}^{v(x)} f(t) dt?

Split the integral: g(x)=0v(x)f(t)dt0u(x)f(t)dtg(x) = \int_{0}^{v(x)} f(t) dt - \int_{0}^{u(x)} f(t) dt. Then, g(x)=f(v(x))v(x)f(u(x))u(x)g'(x) = f(v(x))v'(x) - f(u(x))u'(x).

How do you evaluate ddx2x3cos(t)dt\frac{d}{dx} \int_{2}^{x^3} \cos(t) dt?

Apply the Fundamental Theorem of Calculus and the chain rule: cos(x3)cdot3x2\cos(x^3) cdot 3x^2.

How do you find F(x)F'(x) if F(x)=5x(t2+1)dtF(x) = \int_{5}^{x} (t^2 + 1) dt?

Apply the Fundamental Theorem of Calculus: F(x)=x2+1F'(x) = x^2 + 1.

How do you solve for g(2)g'(2) if g(x)=1x2tdtg(x) = \int_{1}^{x^2} \sqrt{t} dt?

First find g(x)=x2cdot2x=xcdot2xg'(x) = \sqrt{x^2} cdot 2x = |x| cdot 2x. Then, g(2)=22cdot2(2)=8g'(2) = \sqrt{2^2} cdot 2(2) = 8.

How do you find the derivative of x0et2dt\int_{x}^{0} e^{t^2} dt?

Switch the bounds and apply the Fundamental Theorem of Calculus: 0xet2dt-\int_{0}^{x} e^{t^2} dt, so the derivative is ex2-e^{x^2}.

How do you find h(x)h'(x) if h(x)=sin(x)3t3dth(x) = \int_{\sin(x)}^{3} t^3 dt?

Switch the bounds: h(x)=3sin(x)t3dth(x) = -\int_{3}^{\sin(x)} t^3 dt. Apply the Fundamental Theorem of Calculus and the chain rule: h(x)=(sin(x))3cos(x)h'(x) = -(\sin(x))^3 \cos(x).
