Conditional statement
Definition
A conditional statement is a logical proposition that asserts the truth of one statement based on the truth of another. It typically takes the form 'if P, then Q,' where P is a hypothesis and Q is a conclusion.
5 Must Know Facts For Your Next Test
- Conditional statements are essential in proving limits rigorously using the epsilon-delta definition.
- In the context of limits, 'if' represents assuming an arbitrary positive number (epsilon), and 'then' signifies finding a corresponding delta.
- The hypothesis (P) usually involves $|x - c| < \delta$, while the conclusion (Q) involves $|f(x) - L| < \epsilon$ for limits.
- Understanding how to construct and interpret conditional statements is crucial for solving limit problems analytically.
- Failure to correctly formulate or manipulate conditional statements can lead to incorrect conclusions about limits.

Epsilon-Delta Definition: A formal definition of a limit stating that for every positive number epsilon, there exists a positive number delta such that if $0 < |x - c| < \delta$, then $|f(x) - L| < \epsilon$.
Hypothesis: The part of a conditional statement that follows 'if'; it represents an assumption or condition assumed to be true.
Conclusion: The part of a conditional statement that follows 'then'; it represents what follows if the hypothesis holds true.
