Form: (\fracdydx + P(x) y = Q(x))

If you see a function and its derivative, substitute u .

Multiply by the conjugate expression to rationalize radical terms. Continuity Conditions A function is continuous at a specific point if it simultaneously satisfies three conditions: is defined. Asymptotes Vertical Asymptotes: Occur at Horizontal Asymptotes: Occur at

This chapter establishes the analytical foundation for calculus by defining how functions behave as they approach specific points. Left-Hand and Right-Hand Limits
