(a) Vector E has magnitude 50.0 and is directed 40.0° counterclockwise from the +x axis. Express it in unit-vector notation.

(b) Vector F has magnitude 50.0 and is directed 40.0° counterclockwise from the +y axis. Express it in unit-vector notation.

(c) Vector G has magnitude 50.0 and is directed 40.0° counterclockwise from the -y axis. Express it in unit-vector notation.

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
