How do I solve this? A basic physics problem?

Question

I was wondering if anyone could please assist me in understanding and solving the following problem. I have no idea where to even start or what sort of methods to use. I just started college physics and don't want to start not knowing how to solve the early problems.:

a. Vector E has a magnitude 17.0 cm and is directed 27.0* counterclockwise from the +x axis. Express it in unit-vector notation.

b. Vector F has magnitude 17.0 cm and is directed 27* counterclockwise from the +y axis. Express it in unit-vecotr notation.

c. Vector G has a magnitude of 17.0 cm and is directed 27* clockwise from the -y axis. Express it in unti-vector notation.

Any and all help will be much appreciated!!

Answer 1

"units=cm"

Expressed in unit vector notation:standard basis

17* Cos(27)i+ 17* Sin(27)j

a. Vector E=15.147i+7.719j

  

17* Cos(117)i+17* Sin(117)j

b. Vector F=-7.718i+15.147j

17* Cos( 243)i+ 17* Sin(243)j

c. Vector G=-7.718i+(-15.147)j

any more detail, let me know
