Limit Calculator

The function whose limit you want. It may be undefined at the approach point itself — that is exactly when limits are interesting, as with sin(x)/x at 0.

The variable that approaches the point. Other letters in the expression are treated as constants.

The value the variable tends to. Use a number, pi, or oo / -oo for limits at plus or minus infinity.

• Two-sided: both one-sided limits must exist and agree, otherwise the limit does not exist.
• From the left: approach with values smaller than the point.
• From the right: approach with values larger than the point.
