To divide each element of exp(x) by the corresponding element of sin(x), use the ./ operator instead of the / operator. The extra period is important. See this documentation page for a description of the difference.
Because exp(x) for those negative x values is going to be small but exp(x) for those positive x values is going to be large, and because you're using a very coarse grid of x values, there's not a whole lot of detail in the left part of that plot. Maybe you should plot the portion of the graph for negative x on one axes (maybe a subplot axes) and plot the portion of the graph for positive x on a different axes.
