Calculus Problems: Integrals, Derivatives, and Area Calculation
Let f(x) = -x2 + 2x + 3. The graph of f is shown in the following diagram.
(a) Find ∫(-x2 + 2x + 3) dx
(b) Find the area of the shaded region.
2. Let f'(x) = 3x2 – 3. Given that f(2) = 1, find
Vernier Caliper: Understanding Measurement and Usage
Scale in Millimeters
The degree of precision is calculated by dividing the smallest size of the major scale by the number of divisions of the vernier.
Vernier Markings
The vernier may have the following markings:
Reading Underground Foot Measurements
To see if the tube foot is graduated in the English system or the metric system, look for 10 divisions of the major scale, starting from zero.
- If this division is not numbered, it means that the instrument belongs to the English system.
- If compared to Division
Understanding Data Structure in Statistics
What is the Structure of Information?
Data consists of the unit of analysis, the variable, and the category. Data are the raw materials with which statistics work. Statistical processes transform data into useful information. Data extracted from reality should be the most appropriate data for the objectives of the work to be done.
Example: “Luis is 1.70 Meters Tall”
Identify the data, the unit of analysis, the variable, and the category in the following example: “Luis is 1.70 meters tall.”

Primary and Secondary Data Sources: Collection Methods
Primary and Secondary Data Sources
Primary Source
Definition: Data collected directly from the original source.
Description: First-hand data gathered specifically for the current investigation.
Example: Surveys, interviews, and experiments conducted by the researcher for their own research purpose.
Secondary Source
Definition: Data that already exists and was collected for a different purpose.
Description: Second-hand data gathered by others and used for a new analysis.
Example: Reports, academic papers,

Math Problem Solutions
Solving Equations
21: Adding the two equations and dividing by 10, we get: x + y = 10. Subtracting the two equations and dividing by -2, we get: x – y = 1. Solving these two new equations, we get, x = 11/2.
Geometry and Circles
30: Let ABCD be the rhombus circumscribing the circle with center O, such that AB, BC, CD, and DA touch the circle at points P, Q, R, and S respectively. We know that the tangents drawn to a circle from an exterior point are equal in length.
