# An odd definition

The functions y=t , y=sin(t), y=t^3, y=t^5, y=sinh(t) (use sinh(t)=0.5*(e^t-e^(-1*t)) are said to be odd because if they are reflected in the y axis they result in an upside down version of the original graph. This property can be expressed as: y(-t)=-y(t).

To check this graphically, plot the graph of an odd function, y(t), and then enter a new function, replacing t by -1*t in your original function definition, to plot the graph of y(-t).

The second graph should be an upside down version of the original one.
