Question

Find the equivalent equation in rectangular form.
r(cos(theta)-sin(theta))=4

Answer 1

z^1 ?

Answer 2

cos(t)-i sin(t) = 4 maybe

Answer 3

what is rectangular form?

Answer 4

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

r tends to be a radial measure of this is going from polar to a more normal equation

Answer 5

r = sqrt(x^2+y^2)

Answer 6

\[\sqrt{x^2+y^2}(x-y)=4\]
should be it then

Answer 7

\[x=r\cos(\theta)\]\[y=r\sin(\theta)\]so:\[r(\cos(\theta)-\sin(\theta))=4\]becomes:\[x-y=4\]

Answer 8

..... soo close :)
