HP 50g manual Lim f

Function lim is entered in ALG mode as lim(f(x),x=a) to calculate

the limit	lim f (x)	. In RPN mode, enter the function first, then the
	x→a

expression ‘x=a’, and finally function lim. Examples in ALG mode are shown next, including some limits to infinity, and one-sided limits. The infinity symbol is associated with the 0key, i.e.., „è.

To calculate one-sided limits, add +0 or -0 to the value to the variable. A “+0” means limit from the right, while a “–0” means limit from the left. For

example, the limit of x − 1 as x approaches 1 from the left can be determined with the following keystrokes (ALG mode):
