[slim juniper]

dont even know where to begin with this one

[slim juniper]

optimizing theta

[candid mulch]

try drawing triangles from the point where x meets the circle to the center, and then split that traingle in 2 by drawing a perpendicular bisector from the center

you can also use, a triangle inscribed in circle with onse sode asdiameter substends a right angle on the circumference

then you can use trigonometry

[slim juniper]

x=7costheta

and y=7theta

i think?

[bright rivet]

no

how did you get that?

[keen plover]

do you know the formula for arclength?
