Can anyone provide me with the formula to caculate tool offset to machine a degree with a round insert?

For example I want to machine a 36.2" x 10 degree OD with a 1/2" rd insert. How can I calculate where to start the X axis with the Z starting at 0.1? I know it would be easier to use tool nose radius comp (G41 & G42) but I would like to know the formula. Thanks

for z axis-Nose radius x tan(angle/2)

for x axis-Nose radius x tan(45-(angle/2)

angle is from linear

i will provide a link because i had the exact same question not 2 weeks ago.
