OpenStudy (anonymous):

1/2

OpenStudy (bohotness):

did you try look up their answer and keeping going?

OpenStudy (anonymous):

?

OpenStudy (bohotness):

his problem seems a bit far-fetched to me, because the exact values of this particular sin and cos are easily found. You might know them: cos135°=−122√, sin135°=122√, So the answer is 1 - - 1 = 2. I cannot see how half-angle formulas would be of help here... .-. what is close to that

OpenStudy (anonymous):

Im bout to close this thread

OpenStudy (bohotness):

its a god
