(13) (14) WebThe value of tan pi/8 can be calculated by constructing an angle of π/8 radians with the x-axis, and then finding the coordinates of the corresponding point (0.9239, 0.3827) on the unit circle. The value of tan pi/8 is equal to the y-coordinate (0.3827) divided by the x-coordinate (0.9239). ∴ tan pi/8 = 0.4142.
