Reviewing homework and determining the existence of tangent lines in calculus. Explore where tangent lines exist, such as corners and cusps, and where they do not, like at discontinuities and vertical tangents. Investigate if a function has a tangent line at x=2. Solve problems involving rocket height and climbing speed. Homework includes solving specific exercises and preparing for Chapter 2 Test.
