Exact Value Of Cos 7pi 4

To find the value of cos 7π/4 using the unit circle: Rotate ‘r’ anticlockwise to form 7pi/4 angle with the positive x-axis. The cos of 7pi/4 equals the x-coordinate (0.7071) of the point of intersection (0.7071, -0.7071) of unit circle and r. 1 Answer Nghi N. May 3, 2015 cos[ 7π 4] = cos(2π − π 4) = cos( − π 4) = cos( π 4) = sqr2 2 Answer link cos [ (7pi)/4] = cos (2pi - pi/4) = cos (-pi/4) = cos (pi/4) = (sqr2)/2
