Learned how to write the equation of the normal line (exactly like writing the tangent line, except you make the slope perpendicular...normal is a synonym for perpendicular). See notes if you were out during DS.
In class, previewed 3rd quarter topics and began related rates using the DREDS process (Diagram, Rates, Equation, Differentiation, Substitution). Worked through several examples dealing with spheres and circles.
