Nov 5th 2013, 05:43

1. 試求(sin5度- csc5度)的二次+(cos5度- sec5度)的二次 - (tan5度)的二次 - (cot5度)的二次=?

2. 若cosθ+cos的二次θ=1,則sin的二次θ+sin的六次θ+sin的八次θ=?

3. 求(1+tanθ+secθ)(1+cotθ-cscθ)=?

4. 試求sin1度+sin2度+sin3度+......+sin360度之值。

5. 若2+cos的二次θ=7sinθcosθ,0<θ<π/4,試求tanθ之值。

6. 試求cot15π/4 tan(-5π/4) + sin(-5π/3) cos7π/6 + cos(-π/2) sin(-π)=?
