The degree is 45° Explain to your partner how to identify the cosine and sine of the angle from Task A. Then have your partner summarize this in a sentence below: • cos θ = ______ • sin θ = ______ • How did we find the cosine and sine of the angle on the Unit Circle? __________________________________________________________________________________________________________________________________

√2/2, √2,2

OpenStudy (anonymous):

√2/2*

jimthompson5910 (jim_thompson5910):

yep, both have the same coordinates

jimthompson5910 (jim_thompson5910):

the x coordinate of the point on the unit circle is equal to cos(theta) the y coordinate of the point on the unit circle is equal to sin(theta)

OpenStudy (anonymous):

So the cos(theta) would be √2/2 and do would sin(theta)?

OpenStudy (anonymous):

so*

jimthompson5910 (jim_thompson5910):

yep both are equal to one another and equal to that value you wrote

OpenStudy (anonymous):

Okay thank you :)
