x & y Components

a) What is the x-component of vector E of the figure in terms of the angle θ and the magnitude E?
= -Ecosθ

b) What is the y-component of vector E of the figure in terms of the angle θ and the magnitude E?
= Esinθ

c) For the same vector, what is the x-component in terms of the angle ϕ and the magnitude E?
= -Esinϕ
d) For the same vector, what is the y-component in terms of the angle ϕ and the magnitude E?
= Ecosϕ

Brief Explanation:

To get the sin or cos just go over the SOHCAHTOA rule
