1.	Given ā = i + 2; and b = 2i + jwhat are the magnitudes of the two vectors? Are these two vectors equal
Answer» $= \sqrt{ {a}^{2} + {b}^{2} + 2ab \cos( \theta) }$ $\sqrt{ {3}^{2} + {3}^{2} + 18 }$ $= \sqrt{36}$ $= 6$

Answer»

$= \sqrt{ {a}^{2} + {b}^{2} + 2ab \cos( \theta) }$

$\sqrt{ {3}^{2} + {3}^{2} + 18 }$

$= \sqrt{36}$

$= 6$
