## 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?**

**= **-Esin**ϕ**

**d) For the same vector, what is the y-component in terms of the angle ϕ and the magnitude E?
=** Ecos

**ϕ**

Brief Explanation:

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