in which quadrant?

OpenStudy (anonymous):

quadrant two

OpenStudy (anonymous):

can you see the two pics?

OpenStudy (mathmate):

use the identity to find sine. \[sin^2(x)+cos^2(x)=1\] If theta is in quadrant 2, then sin(theta) is positive.

OpenStudy (anonymous):

so is it 3/5?

@jim_thompson5910 ???

jimthompson5910 (jim_thompson5910):

you both are correct

OpenStudy (anonymous):

@jtryon ?

OpenStudy (anonymous):

really?

jimthompson5910 (jim_thompson5910):

\[\Large \sin(\theta) = \frac{3}{5}\] is correct

OpenStudy (anonymous):

so its not 2/5?

jimthompson5910 (jim_thompson5910):

nope

OpenStudy (anonymous):
