Write expressions for all of the four functions using the function sine.

The image below shows a ‘wave mesh’ made with the graphs of the functions a, b, c and d with variable x in radians. [img] – Write expressions for all of the four functions using the function sine. This means that the graphs above are geometrical transformations of the graph of y=sin(x). – Write expressions for all of the four functions using the function cosine. This means that the graphs above are geometrical transformations of the graph of y=cos(x). – Add to the ‘wave mesh’ pattern by translating the mesh in the x-direction by /4 and /4 unit. Show these in a sketch that includes the graphs above, all labelled. Give expressions for such functions. Give the tables of values for one of the functions.
