Question

Shay created the table below to graph the equation r-3-sin theta (rounded to the hundredths place). Analyze the table. Did Shay make a mistake? If there is a mistake, which point is incorrect?

Answer 1

B is the correct answer

Explanation:

Just took the test

Answer 2

B is false

Explanation:

Let's check Shay's table:

• if
  `\theta=0,` then
  `r=3-\sin 0=3-0=3` (true);
• if
  `\theta =(\pi)/(6),` then
  `r=3-\sin (\pi)/(6)=3-(1)/(2)=2.5` (true);
• if
  `\theta = (\pi)/(4),` then
  `r=3-\sin (\pi)/(4)=3-(√(2))/(2)\approx2.29` (true);
• if
  `\theta=(\pi)/(3),` then
  `r=3-\sin (\pi)/(3)=3-(√(3))/(2)\approx 2.13` (false);
• if
  `\theta =(\pi)/(2),` then
  `r=3-\sin (\pi)/(2)=3-1=2` (true).
