General Formulas and Concepts:
<u>Algebra I</u>
Exponential Rule [Dividing]: <u>Calculus</u>
Limits
Limit Rule [Variable Direct Substitution]: Series Convergence Tests
P-Series: Direct Comparison Test (DCT) Limit Comparison Test (LCT): Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
<u>Step 2: Apply DCT</u>
Define Comparison: [Comparison Sum] Simplify: [Comparison Sum] Determine convergence: Set up inequality comparison: [Inequality Comparison] Rewrite: [Inequality Comparison] Simplify: ∴ the sum is divergent by DCT.
<u>Step 3: Apply LCT</u>
Define: Substitute in variables [LCT]: Simplify: [Limit] Evaluate [Coefficient Power Rule]: ∴ Because and the sum diverges by DCT, also diverges by LCT.
