Parametric Equations, The plot above is created with the parametric equations x(t)=acos(bt)
y(t)=csin(dt)
To acheive this graph,

Do you have answer choices?

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.

1. 3/6 or 1/22. 1/123. 1/84. 1/105. 2/12 or 1/6
