Question
Simplify (cos13°+sin 13°)
/(cos13°-sin13°)Solution
(cos13°+sin 13°) /(cos13°-sin13°) [(cos13°+sin 13°)/cos13°] /[(cos13°-sin13°)/cos13°] =(1+tan13°)/ (1-tan13°)        Put tan 45° in place of 1. =(tan45°+tan13°)/(1-tan13°×tan45°) Using the tangent addition formula:  tan(a+b) =(tanA+tanB)/ (1-tanA.tanB) =tan (45°+13°) =tan (58°)
