Let rcostheta Find the horizontal and vertical tangent lines to the polar curve. Enter your answers as a commaseparated list. horizontal tangentsy vertical tangentsx Express dydx as a function of theta using the chain rule and the fact that r is given as a function of theta What is the value of dydx for a horizontal tangent? What does this imply about dydtheta What happens to dydx at vertical tangents? What does this imply about dxdtheta For a value of theta that yields an indeterminate form for dydx how can L'Hospital's Rule be used to evaluate the limit
