In this lesson, we will learn how to find the equations of tangents and normals to trigonometric, parametric, and implicitly defined curves using derivatives.

Lesson Plan

Students will be able to

  • find tangents and normals to trigonometric and reciprocal trigonometric curves,
  • find tangents and normals to parametric curves,
  • find tangents and normals to curves using implicit differentiation,
  • prove that two curves intersect orthogonally,
  • solve word problems using tangents and normals to curves.
