Mastering limits is one of the most important foundations in calculus. Before derivatives and integrals, you must understand how expressions behave as a variable approaches a value, not just plug in numbers, but reason mathematically. In this lesson, I solve the limit: Limp→0 [(2 p)^2 - 4]/p Rather than jumping straight to formulas, I break down the algebra step-by-step, simplify the expression, and show how this problem connects to future concepts like derivatives and the definition of instanta
