How do you find an AVERAGE rate of change of a function f(x) on the interval [a,b]?
|
f(b)-f(a)/b-a
|
|
|
How do you find an instantaneous rate of change of a function f(x) at a point?
|
Find f'(x) and plug in the coordinates of the point.
|
|
|
How do you find the derivative using the limit process?
|
f'(x)=lim f(x+a)-f(x)/a
x-a |
|
|
What are the rules for horizontal asymptotes?
|
If the degree on top is larger...then none.
If the degree on top is smaller....then zero. If the degrees are the same on the top/bottom...then ratio of lead. coefficients. |
|
|
What is removable discontinuity?
Describe analytically & graphically. |
Analytically....you can remove common factors.
Graphically....there is a hole in the graph. |
|
|
What is nonremovable discontinuity?
Describe analytically & graphically. |
Analyticall....you cannot remove common factors.
Graphically....there is no way to make the function continuous (vertical asymptote, jump, oscilation.) |
|
|
When does a limit exist?
|
When the limit from the right equals the limit from the left.
|
|
|
How do you find vertical asymptotes?
|
Factor the rational expression and look at the factors in the denominator. If no factors cancel with the numerator then the vertical asymptotes are the values of x that make the denominator equal to zero.
|
|
|
How do you find the slope of a normal line?
|
Find the slope of the tangent line and take the negative reciprocal.
|
|
|
What is displacement?
|
The change in position over time. (Delta s)
The antiderivative of velocity. |
|
|
What is velocity?
|
The derivative of position or the antiderivative of acceleration.
|
|
|
What is acceleration?
|
The derivative of velocity.
|
|
|
How do you find total distance traveled when given a velocity function?
|
Integrate the absolute value of velocity.
|
|
|
How do you find the displacement of an object when given a velocity function?
|
Integrate the velocity function.
|
|
|
What is the process when differentiating implicitly?
|
1. Differentiate both sides with respect to x. (Remember to attach a y prime when differentiating y terms.)
2. Collect y prime terms on the left side of the equation. 3. Factor out y prime. 4. Solve for y prime. |
