ikram002p · Answer

no he dnt ^^

ikram002p · Answer

and no im not free :)

ganeshie8 · Answer

lol thats funny :) ok let me show u bquick how to do this

ganeshie8 · Answer

wat you're given is simply $(r, \theta) = (8, 30)$

ganeshie8 · Answer

$i$ and $j$ are the x and y components of that polar representation

anonymous · Answer

x = r cos(theta)
y = r sin(theta)

ganeshie8 · Answer

so, 
$i = x =r \cos \theta =  8*\cos  30 = ?$  
$j = y =r \sin \theta =  8*\sin  30 = ?$

anonymous · Answer

i=1.23?
j=-7.90?

ganeshie8 · Answer

i=8*cos(30) = 8*sqrt(3)/2 = 4sqrt(2)

ganeshie8 · Answer

j=8*sin(30) = 8*1/2 = 4
