Make the expression negative because sine is negative in the fourth quadrant. For sin pi, the angle pi lies on the negative x-axis. Letting $x_n = 2\pi e_n$, we see, from our first lemma: … Just for laughs, we can at least in principle compute cos(π / 7) by observing that. If you ever need to compute sin (x*pi) or cos (x*pi), its better to do sinpi (x) or cospi (x).
… The correct option is A 5 16π 5, 4π 5 and 2π 5, 3π 5 areSupplementary angles, sosin 4π 5 =sin(π− π 5)= sin π 5Similarly,sin 3π 5 =sin 2π 5So,sin π 5sin 2π 5sin 3π 5 sin 4π 5 = sin2 π 5sin2 2π 5. … total steps = 2pi / 1.
