Section 6.4: Parametric Equations and Further Graphing
1) Graph the plane curve defined by the parametric equations x = 125cos t and y = 125sin t.
2) Eliminate the parameter t from the parametric equations x = 3cos t and y = 2sin t.
3) Eliminate the parameter t from the parametric equations x = 3 + sin t and y = cos t – 2.
4) Eliminate the parameter t from the parametric equations x = 3 + 2sec t and y = 2 + 4tan t.
5) Graph the path of the human cannonball if the initial velocity out of the cannon is 50 miles
per hour at an angle of 60° from the horizontal.
