Question

Eliminate the parameter to find a Cartesian equation of the curve.

Answer 1

\[x=\sin \frac{ 1 }{ 2 }\theta\]
\[y=\cos \frac{ 1 }{ 2 }\theta\]
in −π ≤ θ ≤ π

Answer 2

square and add.

Answer 3

@random231 do u know what −π ≤ θ ≤ π looks like on a graph?

Answer 4

for (b) Sketch the curve and indicate with an arrow the direction in which the curve is traced as the parameter increases.

Answer 5

−π ≤ θ ≤ π is not a curve @Zenmo its a condition

Answer 6

what does the condition look like then?

Answer 7

actually, what does a negative unit circle look like?
