Hard

Find derivatives using the limit definition (Hard)

23 problems · 25-30 minutes · Skills: derivatives, calculus, limits

About This Worksheet

This hard-level worksheet contains 23 problems designed for 12th Grade students practicing definition of the derivative. Hard worksheets feature challenging problems including multi-step questions, missing values, and real-world applications to push students further.

The limit definition of the derivative is the conceptual heart of differential calculus. Understanding it — not just the computational shortcut rules — is what allows students to understand why the rules work, to derive new rules, and to apply the derivative meaningfully in novel situations.

  • Define the derivative as the limit of the difference quotient
  • Compute derivatives of simple functions using the limit definition
  • Interpret the derivative geometrically as the slope of the tangent line and physically as instantaneous rate of change
  • Use the definition to show that a function is differentiable at a given point
  • Explain why a corner or cusp makes a function non-differentiable at that point
