Describe fully the sequence of two transformations that maps the graph y = sinx onto the graph of y = 3sin2x

Well I know that when x = 45 y = 3, when x = 90 y = 0 when x = 135 y = -3 and so on, but tranformations and translation (move), reflection, rotation and englargment. I would presume that the graph is enlarged and then relected, however what is the point of enlargment?

Am I right so far?

Thanks
