Sin pi/8 - Find Value of Sin pi/8 Sin π/8 - Cuemath
WebUse the half-angle formulas to find the exact value of the trigonometric function tan 5 pi/8 (tan 5π/8). This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Web⇒ tan π 8 = − 1 ± √ 2 But tan π 8 = − 1 − √ 2 is not possible as π 8 lies in the first quadrant and tan is positive in first quadrant. ∴ tan π 8 = − 1 + √ 2 = √ 2 − 1 WebHow do you express tan( 519π) as a trig function of an angle in Quadrant I? −tan(5π) Explanation: tan( 519π) = tan(−5π +205π) = tan(−5π + 4π) = ...
