Question 2

On a new script;

a)

(i) Create a variable x, ranging from 0 to 2*pi having 40 elements/points

b)

(ii) Plot y1 = sin(x)

(iii) Add a title and axis labels to your graph. (iv) Plot y2 = cos(x).

(v) Add a title and axis labels to your graph.

(vi) Plot both y1 & y2 on the same graph. y1 should appear cyan with dotted lines while y2 should

appear green with starred lines.

(vii) Add a title and axis label to your graph.

(i) Create a subplot that will plot y1 against x on the first, y2 against x, y1 & y2 against the x on the third and y3=tan(x) against x on the fourth

(ii) Add a color and symbol to each subplot.

(iii) Add a comment beside each plot command.
