Question

Change these polar equations to rectangular form θ = 135°

Answer 1

\[\Large\bf\sf \arctan\left(\frac{y}{x}\right)\quad=\quad \theta\qquad\implies\qquad \tan 135^o\quad=\quad \frac{y}{x}\]
\[\Large\bf\sf y=(\tan 135^o) x\]

Answer 2

Hmm that's kind of confusing to do it that way ^
lemme draw a graph instead.

Answer 3

So your good at these? i have one more
