Question

Vector problem, I have to draw it though...

Answer 1

a = <2,pi/3> b = <3,3pi/4> c= <1,pi/6>

Write down a,b,c in terms of i and j

Get a +c in terms of i and j

Answer 2

This is similar to a recent question, the notation is <magnitude, angle>

Answer 3

\[a+c = <2+1,\frac{(2)pi}{(2)3}+\frac{pi}{6}>\]
\[a+c = <3,\frac{3pi}{6}>\]
\[a+c = 3i+\frac{pi}{2}j\]

Answer 4

<xpart, ypart> is vector notation

Answer 5

vector equivalent of polar cordinates ; now theres something to write home about :)

Answer 6

x = r cos(t) ; y = r sin(t)

Answer 7

r is given and t is givne

Answer 8

\[a+c=<1,\sqrt{3}>+<\frac{1}{2},\frac{1}{\sqrt{3}}>\]
\[a+c=<1+\frac{1}{2},\sqrt{3}+\frac{1}{\sqrt{3}}>\]
\[a+c=(1+\frac{1}{2})i +(\sqrt{3}+\frac{1}{\sqrt{3}})j\]

Answer 9

a= i + sqrt3 j

Answer 10

right

Answer 11

i forgot the middle of the question :)

Answer 12

b = -3/sqrt2i +3/sqrt2j

Answer 13

c= sqrt3/2i + 1/2j

Answer 14

c = cos(30)i + sin(30)j
