What does the derivative of a function represent

The derivative of a function represents the instantaneous rate of change with respect to its independent variable

2
New cards

How can the derivative be used in applied contexts

The derivative can be used to express information about rates of change in applied contexts.

3
New cards

What is the unit for f′(x) in relation to the units of F and xxx?

The unit for f′(x) is the unit for f divided by the unit for x.

4
New cards

How can the derivative be applied to rectilinear motion problems?

The derivative can be used to solve rectilinear motion problems involving position, speed, velocity, and acceleration.

5
New cards

What kind of problems can be solved using the derivative?

The derivative can be used to solve problems involving rates of change in applied contexts.

6
New cards

What is the chain rule used for in related rates problems?

The chain rule is used for differentiating variables in a related rates problem with respect to the same independent variable.

7
New cards

Which other differentiation rules might be necessary in solving related rates problems?

Other differentiation rules, such as the product rule and the quotient rule, may also be necessary to differentiate all variables with respect to the same independent variable.

8
New cards

How can the derivative be utilized in related rates problems?

The derivative can be used to solve related rates problems by finding a rate at which one quantity is changing by relating it to other quantities whose rates of change are known.

9
New cards

What does the tangent line represent in relation to a function?

The tangent line is the graph of a locally linear approximation of the function near the point of tangency.

10
New cards

How does the behavior of a function near the point of tangency affect the tangent line approximation?

The function’s behavior near the point of tangency may determine whether a tangent line value is an underestimate or an overestimate of the corresponding function value.

11
New cards

What are indeterminate forms in limits?

When the ratio of two functions tends to 0/0 or ∞/∞ in the limit, such forms are said to be indeterminate.

12
New cards

How can indeterminate forms 0/0 or ∞/∞ be evaluated?

Limits of the indeterminate forms 0/0 or ∞/∞ may be evaluated using L’Hospital’s Rule.
