The locators on the left determine a rectangle in the complex plane; the image of the rectangle under the selected function is shown on the right. The locators snap to the grid, allowing easy selection of natural domains for these functions. Appropriate branches of the
log
,
arcsin
, and
arccos
map a range on the right to the corresponding domain on the left.
