the goal is to find the coordinates of the point at the end of that angle. We are told that y = 1 at that point so we just need to find the x coordinate and we're set
to do this we use the triangle that is made when you draw a line straight down from the point like I have in the drawing

we know the length of that side is one because we were told that y = 1
now if we knew the angle inside that triangle we could use the tangent function to find the length of the adjacent side, which I labelled x.
any idea how we can find it?
tan 3pi/4=1/x?
nope, you used the wrong angle, we need to find the angle inside that triangle
|dw:1350328078591:dw|
the 3pi / 4 is outside the triangle
If I use the Unit Circle and says that 3pi/4 is 135... and I am looking for that inside angle I get that it is equal to 45.

right, so now we can use tangent to find x \[\tan(45) = \frac{ 1 }{ x }\]
isolate x and you've got it
x=-1?
yep!
got it... thanks!
how is x= -1?
So the point would be (-1, 1)?
