Missing parts
  1. Answer
    cos^2 x
    Choices
    1. cos^2 x
    2. tan^2 x
    3. sec^2 x
  2. Answer
    cos x
    Choices
    1. cos x
    2. tan x
    3. cot x
  3. Answer
    cos x
    Choices
    1. cos x
    2. sin x
    3. sec x
Complete the statement
sin^2 x + {0} = 1. Also sin 2x = 2 sin x {1}. And tan x = sin x / {2}.
