Question

Write -3R + 7U in polar form

Answer 1

What do your "R" and "U" refer to? Such symbols are new to me.

Give an example of what a quantity in "polar form" looks like.

Answer 2

Rectangular to polar coordinates, you use tangent i think

Answer 3

\[-3R+7U\] is meaningless without knowing what R and U are, what @mathmale said

Answer 4

U is like x & y, R is like 0

Answer 5

R is tangent I mean

Answer 6

So then...\[-3U+7R\rightarrow-3\tan{\theta}+7(xy)\]Is this it?

Answer 7

yes

Answer 8

Eh... that's odd o_e
