Study Notes
Geometric Sequence
- Each term is generated by multiplying the previous term by a constant factor.
- Important in various fields like finance and biology for modeling exponential growth.
Arithmetic Sequence
- Each term is formed by adding a constant to the previous term.
- Commonly used in daily life scenarios, such as calculating total costs or time increments.
Recursive Definition
- A method for defining sequences where each term is based on preceding terms.
- Useful in programming and mathematical concepts for defining functions.
Exponential Graph
- Characterized by a J-shaped curve, indicating rapid growth.
- Commonly found in real-world situations such as population growth and investment returns.
Linear Graph
- Represents a straight line, indicating a constant rate of change.
- Used to model relationships with linear behavior, such as distance over time.
Growth Factor and Rate of Change
- Growth Factor: Involves multiplication, indicating the scale of growth.
- Rate of Change: Involves addition, showing the linear increment in values.
Recursive Example (Geometric)
- A specific sequence given as: 2, 6, 18, 54.
- Defined recursively as A(1)=2 and A(n)=A(n-1)x3 for n≥2, illustrating exponential growth.
nth Term Example (Geometric)
- Example sequence provided: 160, 40, 10, 2.5.
- nth term defined as A(n)=160(1/4^n) for n≥0, demonstrating the decrease in values.
Recursive Example (Arithmetic)
- Sequence shown: 2, 7, 12, 17.
- Defined as A(1)=2 and A(n)=A(n-1)+5 for n≥2, representing a linear increment.
nth Term Example (Arithmetic)
- Example sequence given: 9, 5, 1, -3.
- nth term formula: A(n)=9-4n for n≥0, indicating a consistent negative trend.
Volume of an Open-Top Box
- Volume formula is V(x)=(l-2x)(w-2x)(x), where length and width are adjusted by side cuts.
- Important in optimization problems in geometry, particularly in design and manufacturing.
Domain for an Open-Top Box
- Defined as 0, indicating the minimum value for dimensions within the context of the volume formula.
- Highlights the practical constraint in real-world applications when constructing objects.
