## Study Notes

### Concept of Limits in Calculus

• Limits define the value a function approaches as the input approaches a certain point.
• Essential for understanding continuity, derivatives, and integrals.

### Single Variable Function

• A function that consists of only one independent variable, such as $f(x) = 2x + 3$.

### Taylor's and Maclaurin Series

• Taylor series represent a function as an infinite sum of terms calculated from the values of its derivatives at a single point.
• Maclaurin series is a special case of Taylor series at the point 0, providing a way to approximate functions using polynomials.

### Leibnitz's Theorem

• Describes the differentiation of products of functions, providing a formula for the nth derivative of a product.

### Mean Value Theorem (MVT)

• States that for a continuous function on a closed interval $[a, b]$ and differentiable on the open interval $(a, b)$, there exists at least one point $c$ in $(a, b)$ where the derivative $f'(c)$ equals the average rate of change over the interval.

### Guarantees of MVT for Differentiable Functions

• Ensures at least one point $c$ exists such that $f'(c) = \frac{f(b) - f(a)}{b - a}$.

### Conditions for Applying MVT

• The function must be continuous on $[a, b]$ and differentiable on $(a, b)$.

### Implications of Average Rate of Change

• If the average rate of change of $f(x)$ on $[0, 4]$ is 3, MVT guarantees there is at least one point $c$ in $(0, 4)$ where $f'(c) = 3$.
