# Formula problem

Is there a way to enter this formula in one cell. It only seems to work if I break it up in to two cells.

=Degrees(atan(slope(a1:a10,b1:b10)))

I am converting the slope of the line into an angle.

It seems to work for me. What error are you getting?

I thought the result was wrong because it seemed different from when I broke it up, but now I am not sure. I am trying to convert the slope of the linear regression line to an angle that runs from +90 degrees to -90 degrees. My approach may be wrong since the result doesn't seem to be right. Something that has doubled in value should have a 45 degree slope, but this is not what I am seeing.
