Misc. Trig

100

y = x

1 = cos(theta) / sin(theta)

200

y = (3x - 12 ) ^ 2

sin(theta) / 72 cos(theta) - 144 / 9 cos^2(theta) = r 

300

2 + y = -4x - 11 / 6 

23 + 6 sin(theta) / 4 cos(theta)  = r 

400

r = 8 / 7 r cos(theta) - 4 r sin(theta)

7x - 4y = 8

500

r = sqrt12 / 8 sec(theta)

x^2 + y^2 = x sqrt12 / 8
