1. explain how you would graph the following set of parametric equations by plotting points and describing the orientation.
x=3t and y=t^2

2. for parametric equations x= a cos t and y= b sin t, describe how the values of a and b determine which conic section will be traced.

the following two sets of parametric functions both represent the same ellipse. explain the difference between the graphs.

11 feet 6 inches and 8 feet 6 inches

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
