The given angle is 225o.
\To find a point on the terminal side of 225o.
\The terminal side of 225o lies along the y =
x.
So, The terminal side coordinates equal then a point (
1,
1).
The distance formula from the origin to (x, y):
.
(Substitute x =
1, y =
1)
The trigonometric functions using the values x =
1, y =
1 and
.
(Substitute
, y =
1)
(Substitute
, x =
1)
(Substitute x =
1, y =
1)
