WitrynaFirst, we recall `tan x = (sin x) / (cos x)`. `tan a/2=(sin a/2)/(cos a/2)` Then we use the sine and cosine of a half angle, as given above: `=sqrt((1-cos a)/2)/sqrt((1+cos a)/2)` Next line is the result of multiplying top and bottom by `sqrt 2`. `=sqrt((1-cos a)/(1+cos a))` We then multiply top and bottom (under the square root) by `(1 − cos ... Witrynasin2 θ means to find the sine of θ, then square the result, and sin θ2 means to square θ, then do the sine function Example: 32° Using 4 decimal places only: sin (32°) = 0.5299... cos (32°) = 0.8480...
