(a) Vector E has magnitude 50.0 and is directed 40.0° counterclockwise from the +x axis. Express it in unitvector notation.
(b) Vector F has magnitude 50.0 and is directed 40.0° counterclockwise from the +y axis. Express it in unitvector notation.
(c) Vector G has magnitude 50.0 and is directed 40.0° counterclockwise from the y axis. Express it in unitvector notation.

I will be happy to critique your thinking.

This is what I went about doing but the signs don't make sense. Thanks for any help!
a.) 50*sin40=y y= 37.25j
50*cos40=x x= 33.35i
b.) 50*sin40=x x= 37.25i
50*cos40=y y= 33.35j
c.) 50*sin40=y y= 37.25j
50*cos40=x y= 33.35i
