· How do you find the exact values of tan pi/ 8 using the half angle formula? · Despite that this form is comparable with the formula sin^(1)xcos^(1)x=pi/2, it is not a formula But the solution exists See TruongSon's answer sin(1)0=npi and tan^(1)0=mpi, where m,n are 0, or any integer So, sin(1)0tan^(1)0= 0, or an integer multiple of pi Despite that the form is comparable with the general formula sin(1)xcos^(1)x=pi/2, there exists uniqueSolution Given tan(pi/8) = Sqrt(A) B (1) tan(pi/8) = sin(pi/8) / cos(pi/8) view the full answer Previous question Next question Transcribed Image Text from this Question If tan pi/8 = Squareroot A B, then, by using a half angle formula, find A =, B =
