recall that
tan(x-y) = (tanx-tany)/(1 + tanx tany)
Use an Addition or Subtraction Formula to write the expression as a trigonometric function of one number.
(tan(74°)-tan(14°))/(1+tan(74°)tan(14°))
=__________
Find it's exact value (not decimal form)
=__________
Note: A similar question(but with different degrees) had the answers for question part 1 and 2 as this
1). tan 30°
2). 1/square root{3}
