Draw the graph of the following function: cos x 2 Also write its range and period.

Let y = cos x 2 x - 2 π - 3 π 2 - π - π 2 0 π 2 π 3 π 2 2 π y - 1 - 1 2 0 1 2 1 1 2 0 - 1 2 - 1 We know that, range of cos α = [ - 1 , 1 ] . ⇒ - 1 ≤ cos x 2 ≤ 1 ∴ Range of cos x 2 = [ - 1 , 1 ] . We know that, period of cos α = 2 π . Period of cos n α = 2 π n . ∴ Period of cos x 2 = 2 π 1 2 = 4 π .
