will award best answer Circular Functions help please ?
The value of the expression: sin(11pi/6) - cos(8pi/3) + tan(3pi/4)
- Wayne DeguManLv 76 months agoFavorite Answer
sin(11π/6) => sin(-π/6) = -sin(π/6) = -0.5
cos(8π/3) => cos(2π/3) = -cos(π/3) = -0.5
tan(3π/4) => -tan(π/4) = -1
Hence, -0.5 - (-0.5) - 1 => -1
