You probably just need x^2 + y^2 = r^2

Sine is pretty easy to approximate.

If the angle is less that 30 degrees then the approximation,

**sin(x) = x**, with x in radians ( equiv to sin(x) = x*pi/180 with x in degrees),

will get you less than 5% error.

If you want better use**sin(x) = x - x^3 / 6** (equiv to six(x) = x*pi/180 - (x*pi/180)^3 / 6 with x in degrees) will get you approx 1% max error if x is less than 60 degrees and better than 0.1% max error if x is less than 30 degrees.

If the angle is less that 30 degrees then the approximation,

will get you less than 5% error.

If you want better use
