ATAN2 function
Arctangent of x- and y-coordinates. ATAN2 works in Sheets with the usual arguments and results, on cells and on live data from the tools you connect.
Syntax
=ATAN2(x_num, y_num) | Argument | Use |
|---|---|
x_num | required |
y_num | required |
On live data
In Sheets, ATAN2 sits next to live data from a connected tool: =data.orders.sum(total) totals a table, =list.orders(customer) spills a column's distinct values, and a linked table column such as table.orders[Total] is a range any function accepts.
