Sec x = 1/Cosx
Pi radians = 180 degress
Pi/12 = 180/12 = 15 degrees.
Sec15° = 1/Cos15°
Sec pi/12 = Sec 15° = 1/Cos 15°
Cos 15° = 0.9659 using a calculator.
Sec pi/12 = Sec 15° = 1/Cos 15° = 1/0.9659 = 1.0353
Sec Pi/12 = 1.0353
4z + 2
2z 8z^2 + 4z - 5
- 8z^2
4z - 5
- 4z
-5
(8z^2 + 4z - 5) ÷ 2z = 4z + 2 R -5
