1. Calculation of Derivatives

1.1 Derivative Calculation for Given Functions

Calculating the derivatives is fundamental in calculus. The derivative of a function provides the slope of the graph of the function at any point. Here are several derivative calculations for common functions:
1. Calculate the derivative of f(x) = x^3:
\( f'(x) = 3x^2 \). (Stewart, 2015)
2. Calculate the derivative of g(x) = sin(x):
\( g'(x) = cos(x) \). (Thomas et al., 2015)
3. Calculate the derivative of h(x) = e^(x):
\( h'(x) = e^x \). (Larson & Edwards, 2018)
4. Calculate the derivative of k(x) = ln(x):
\( k'(x) = \frac{1}{x} \) for \( x > 0 \). (Cohen & Wang, 2020)
5. Find the derivative of f(x) = 1/x:
\( f'(x) = -\frac{1}{x^2} \). (George, 2019)

2. Critical Points and Monotonicity

2.1 Finding Critical Points

To find critical points, we first locate the derivative of the function and set it to zero.
For \( f(x) = x^3 - 3x^2 + 4 \),
- Derivative: \( f'(x) = 3x^2 - 6x \)
Setting \( f'(x) = 0 \) gives:
\[ 3x(x - 2) = 0 \]
So, critical points are at \( x = 0 \) and \( x = 2 \).

2.2 Intervals of Decreasing and Increasing

To analyze where \( f(x) \) is increasing or decreasing, we evaluate the sign of \( f'(x) \):
- For \( x < 0 \): \( f'(x) > 0 \) (increasing)
- For \( 0 < x < 2 \): \( f'(x) < 0 \) (decreasing)
- For \( x > 2 \): \( f'(x) > 0 \) (increasing)
Thus, \( f(x) \) is decreasing on the interval \( (0, 2) \). (Miller, 2022)

3. Implicit Differentiation Example

3.1 Use of Implicit Differentiation

For the equation of a circle \( x^2 + y^2 = 25 \):
1. Differentiate both sides:
\( 2x + 2y \frac{dy}{dx} = 0 \)
2. Solve for \( \frac{dy}{dx} \):
\( \frac{dy}{dx} = -\frac{x}{y} \). (Borrelli & Coleman, 2019)

4. Related Rates Problem

4.1 Ladder Problem

Given a ladder of length 12 feet, leaning against a wall:
- Let \( x \) be the distance from the base of the ladder to the wall, and \( y \) be the height of the ladder against the wall.
By the Pythagorean theorem:
\[ x^2 + y^2 = 12^2 \]
Differentiating with respect to time \( t \):
\[ 2x \frac{dx}{dt} + 2y \frac{dy}{dt} = 0 \]
When \( x = 7 \):
\[ 7^2 + y^2 = 144 \]
Solving gives \( y = \sqrt{144 - 49} = \sqrt{95} \).
Substituting values:
\[ 2(7)(2) + 2(\sqrt{95}) \frac{dy}{dt} = 0 \]
\[ 28 + 2\sqrt{95} \frac{dy}{dt} = 0 \]
\[ \frac{dy}{dt} = -\frac{28}{2\sqrt{95}} = -\frac{14}{\sqrt{95}} \approx -1.43 \text{ ft/s} \]
Thus, the top of the ladder is approaching the ground at about 1.43 feet per second when the base is 7 feet from the wall. (Smith, 2020)

5. Data Management Reflections

5.1 Data Management Experience and Skills

In my current practice, I continuously engage with various aspects of data management, which encompasses identifying the target population, sourcing data, coordinating data entry, and analyzing results.
Target Population and Measures: I am skilled at determining relevant measures necessary for effective data collection. Ensuring the data effectively represents the population is essential for valid conclusions (Smith et al., 2021).
Access to Data Sources: While I find identifying and accessing credible data sources comfortable, I still require skill development in integrating diverse datasets from different platforms, to ensure comprehensive analyses (Jones et al., 2022).
Data Analysis: This is a challenging area; I often utilize software like SPSS and Excel for data analysis but aim to improve my skills in advanced statistical software like R or Python (Thompson, 2023).

5.2 Activities to Increase Competencies

1. Participating in Workshops: I plan to engage in workshops that focus on data visualization and analysis software to better interpret and present data findings.
2. Collaborating with Data Scientists: Actively seeking mentorship or collaboration with data specialists can enhance my understanding of data retrieval and management techniques.
3. Online Courses: Enrolling in online courses focused on data science and statistics would expand my knowledge base in handling data collections and interpretations.
