Chapter 3, Problem 24EAP

a. What is the angle ∮ between vectors $\stackrel{\to }{E}$ and $\stackrel{\to }{F}$ in FIGURE P3.24?

b. Use geometry and trigometry to determine the magnitude and direction of $\stackrel{\to }{G}=\stackrel{\to }{E}+\stackrel{\to }{F}$ .

c. Use components to determine the magnitude and direction of $\stackrel{\to }{G}=\stackrel{\to }{E}+\stackrel{\to }{F}$ .
