The Unit Circle (Per. 3 Team 6) by Crystal Pederson https://padlet.com/cpederson8/32vzhzmpoznqvtma As a team, list as many patterns as you can see on the unit circle that will help you memorize the trig values! Include tips for remembering the tangent values, even if they are not labeled on the picture below. en-us 2022-02-09 17:48:16 UTC 2026-03-25 03:27:13 UTC hello@padlet.com 23emilyncervantes https://padlet.com/cpederson8/32vzhzmpoznqvtma/wish/2041198153 All values across from each other are equal besides positive or negative.]]> 2022-02-10 21:13:04 UTC https://padlet.com/cpederson8/32vzhzmpoznqvtma/wish/2041198153 23emilyncervantes https://padlet.com/cpederson8/32vzhzmpoznqvtma/wish/2041199692 All middle values (any value with a radian with a denominator of 4) equal radian 2/2.
