1) What is the equation csc^2θ = 1+cot ^2θ true for all values of θ
2)What is the solution for 2 cos - √3 =0 for 0 ≤ X ≤ 2π
3) Find the exact value of tanπ/10 + tanπ/15 / 1- tanπ/10 tanπ15
4) prove the identity cosθ - sinθ / cosθ + sinθ = sec2θ - tan2θ
5) What is the solution to the equation cos2X + 2 = sinX for 0° ≤ X ≤ 360°
6) Determine the value of cosθ (sinθsecθ + tanθ / secθtanθ) if sinθ= 13/85 and cosθ = 84/85
