Calc II Exam 2: Study Guide Sections covered in this exam: 11.1 – Parametric Equations 11.2 – Arc Length and Speed 11.3 – Polar Coordinates 11.4 – Areas and Arc Length in Polar Coordinates 12.1 / 12.2 – Vectors in 2D and 3D 12.2 – Vectors in 3 Dimensions 12.3 – The Dot (Scalar) Product 11.1 Parametric Equations Let C be a curve in the plane. A particle’s motion along C can be described by giving its coordinates as functions of time t. x=f(t), y=g(t) The equations above are called parametric equations and t is a parameter for these equations. As t varies, (x, y) varies and traces the parametric curve C. Using substitution to express in form y=f(x): If x=t+3 and y=4t, solve for t so that t=x-3. x=t+3 t=x-3 Then, substitute t into y=4t.
