Answer 1

take the tangent, multiply by 3

Answer 2

i think using calculas

Answer 3

lol
\[x=\arctan(\frac{y}{3})\]
\[\tan(x)=\frac{y}{3}\]
\[y=3\tan(x)\]

Answer 4

oh. but what happened to the arctan??

Answer 5

it is gone, because i took the tangent of both sides

Answer 6

switched the y and x places. tan is opposite opperator of arctan

Answer 7
