WebSep 10, 2016 · 3. If you consider an equilateral triangle ABC whose each side is "a",each angle will be 60 degrees,draw perpendicular from point A on side BC as AD, angle DAB=angle DAC=30 degrees.on calculating geometrically you will get BD=a/2,also AB=a. sinBAD = sin (π/6) = BD/AB = (a/2)/a = 1/2. Share. WebMake the expression negative because sine is negative in the third quadrant. −sin( π 6) - sin ( π 6) The exact value of sin(π 6) sin ( π 6) is 1 2 1 2. −1 2 - 1 2. The result can be shown …
