Sin 3pi 4
Sin (3pi / 4) Please help me !!!!!!!!!!!!!? 3
I don't really understand ___ they said use the unit circle to find the correct values of triangular functions.
updateI'm in the eleventh grade.
3 ft / 4 is in quadrant III and sin is negative in this quadrant.
Sin (3pi / 4) = Sin (pi / 4) = š2 / 2
What grade are you in, maybe I can help?
