Enter into your calculator: Change MODE to PAR (parametric). Use the Y= to type in equations. Use GRAPH to see the graphs, sometimes with ZOOM 6: ZStandard. Try a new WINDOW: Tmin = -2nt and Tmax = 4x. CYCLOID 4. Let x = t - sint 1.53 y =1-cost 0.5 Consider t = 5. Find each of the following. 5 >x (a) x(5) = ( b) J ( 5 ) = (c) Mark the point (x(5) , y(5) ) on the graph. 5. Suppose parametric equations for the line segment between (2,-9) and (9,-8) have the form: [x (t ) = a+bt ly (t ) = c+ dt If the parametric curve starts at (2,-9) when t = 0 and ends at (9,-8) at t = 1, then find a, b, c, and d. 6. Use calculator to graph the following parametric equations: Jx (1) = 1+2sin(21) a ) Jx(1) = 2cos(t) b ) ly (t) = sin (21 ) ly (1) = 1+2 cos(51)
