Draw the graph of [y] = cos x, x in [0, 2pi], where [*] denotes the greatest integer function.

Draw the graph of y = [sin x], x in [0, 2pi], where [*] represents the greatest integer function.

Draw the graph of y = cos^(2)x.

Draw the graph of y= cos(x- pi/4).

Draw graph of y=cos x+|cos x|

Draw the graph of y = sin x + cos x, x in [0, 2pi].

(i) Draw a rough sketch of y = sin 2x and determine the area enclosed by the curve, x-axis and the lines x = (pi)/(4) and x = (3pi)/(4). (ii) Draw the graph of y = cos 3x, 0 lt x le (pi)/(6) and find the area between the curve and the axes.

Draw the graph of y=cos^(-1)(2^(x)) .
