Trace Edge 16.Tap and select Edge.

Now the table shows (if possible) pairs of values that make the relation true. By default, the first column is the Y-column and there are multiple X-columns in case more than one X-value can be paired with the Y-value to make the relation true.

Tap to make the first column an X-column followed by a set of Y-columns. In the figure above, for Y=0, there are 10 values of X in the default Plot view that make the relation Y=SIN(X) true. These are shown in the first row of the table. It can be clearly seen that the sequence of X-values have a common difference of π.

Again, you can enter a value for Y that is of interest.
