Best ResponseYou've already chosen the best response.3It's learning the unit circle I think with emphasis on the angles of the special right triangles.

Best ResponseYou've already chosen the best response.0if i'm not mistaken the two distances than are 5pi/4 and pi/4?

Best ResponseYou've already chosen the best response.3\[\sin \frac{\pi}{4}=\cos \frac{\pi}{4}=\frac{\sqrt{2}}{2}\]

Best ResponseYou've already chosen the best response.3So whenever you have a reference angle of pi/4, the sin and cos will be sqrt2/2 making adjustment for the sign depending on the quadrant.

Best ResponseYou've already chosen the best response.3So if the cos, which is like x, is sqrt2/2, you must be in either quadrant 2 or 3 and the reference angle must be pi/4

Best ResponseYou've already chosen the best response.3And so the distance on the unit circle would be pipi/4 and pi + pi/4 or 3pi/4 and 5pi/4

Best ResponseYou've already chosen the best response.0but speficially for this problem when it refers to the distances they just want (sqrt(2)/2,sqrt(2)/2)?

Best ResponseYou've already chosen the best response.3No. They want the distance traveled on the unit circle.

Best ResponseYou've already chosen the best response.3Or in other words, they want the angle

Best ResponseYou've already chosen the best response.0I put in 5pi/4 and 3pi/4 it said it's incorrect

Best ResponseYou've already chosen the best response.3Well then it must be a formatting problem because if the x value is sqrt2/2, the angles are 3pi/4 and 5pi/4

Best ResponseYou've already chosen the best response.3did you put in the comma?

Best ResponseYou've already chosen the best response.0i put in 3pi/4, 5pi/4

Best ResponseYou've already chosen the best response.0it's right! I probably forgot to add in the comma the first time :) thank you
