Suppose you start at the point(1,0) on a unit circle and move a distance t=3.5 along the circle. What is the reference number for t?

Question

|dw:1443954591287:dw| So we're starting off at $P (1,0)$ and we're looking for  $\mathbf {\overline t}$

jhannybean · Answer

To do that, we're simply going to subtract the distance, $\mathbf t = 3.5$ by $2\pi$ to find $\mathbf{\overline  t}$

jhannybean · Answer

$$\overline t = 2\pi - 3.5 =~?$$ This is what you call the reference number.

anonymous · Answer

would you simply multiply 2(3.14)-3.5?

anonymous · Answer

I got 2.7

jhannybean · Answer

Yeah but I wouldn't limit it to 3.14 unless specifically asked for, it gives an inaccurate reading and the reference number is simply an approximation.

jhannybean · Answer

so $\overline t \approx 2.78$

thank you so much! You literally saved me. I have a quick question about trigonometry and right angles. I know all the angles but don't know any of the sides

jhannybean · Answer

Youre not really giving me any answer choices to work with so I can check whether my solution matches up to any of the choices.

anonymous · Answer

oh there are no answer choices. I'm taking an online program called wamap. I just have to input my answer and see if it's right or not

jhannybean · Answer

This is not a quiz is it?

anonymous · Answer

no it's not it's homework in preparation for the quiz.

jhannybean · Answer

Okay.
