WebRotate ‘r’ anticlockwise to form 7pi/4 angle with the positive x-axis. The tan of 7pi/4 equals the y-coordinate (-0.7071) divided by the x-coordinate (0.7071) of the point of intersection (0.7071, -0.7071) of unit circle and r. Hence the value of tan 7pi/4 = y/x = -1 ☛ Also Check: sec pi/2 sin 5pi/12 csc pi/3 tan 5pi/4 tan pi/4 cos pi/2 WebFind the Exact Value cos ( (7pi)/12) cos ( 7π 12) cos ( 7 π 12) Rewrite 7π 12 7 π 12 as an angle where the values of the six trigonometric functions are known divided by 2 2. cos( …
