To solve this expression, first we need to calculate the values of tangent of 57 and tangent of 27 degrees:
tangent(57) ≈ 1.5403tangent(27) ≈ 0.5095
Now substitute these values into the expression:
(1.5403 - 0.5095) / (1 + 1.5403*0.5095)= 1.0308 / (1 + 0.7859)= 1.0308 / 1.7859≈ 0.5768
Therefore, tg57 - tg27 / 1 + tg57*tg27 ≈ 0.5768.
