Explore sequences in calculus through this 30-minute video tutorial. Learn to write formulas for alternating sequences like {1, -1, 1, -1, ...} and {-1, 1, -1, 1, ...}. Tackle various sequence problems, including finding formulas for patterns such as {1, 2, 3, 4, 5, 8, ...} and {0, 0, 1, 0, 0, 1, ...}. Practice with multiple examples and discover three different formulas for the sequence {0, 1, 0, 1, 0, 1, ...}. Enhance your understanding of sequence notation and problem-solving techniques in calculus.
