It takes 3 arguments: the limiting value of the argument, the method of approach (either null, above, below or both_sides) and the function. The limit of sin(x) as x tends to 0 0 both_sides This symbol is used within a limit construct to show the limit is being approached from both sides. It takes no arguments. The limit of sin(x) as x tends to 0 from either direction 0 above This symbol is used within a limit construct to show the limit is being approached from above. It takes no arguments. The limit of sin(x) as x tends to 0 from above 0 below This symbol is used within a limit construct to show the limit is being approached from below. It takes no arguments. The limit of sin(x) as x tends to 0 from below 0 null This symbol is used within a limit construct to avoid specifying the method of approach to the limit. It takes no arguments. The limit of sin(x) as x tends to 0 0
