Is there a slope formula for calculating horiz tilt in a slope?

[adaugherty]

I'm designing some precast coping for a wall that has a vertical slope from EL.3'-0" up to EL.10-0"
This coping will be sloping in a semi-circle, similar to a spiral staircase.
If I'm not mistaken, this coping will have to tilt inward or twist as it slopes up.
Is there a formula that will give me the amount of twist in ea segment of coping?

Thanks,

I am sorry I can't give direct help, sinc I do not understand what setup of walls you attempt to build.

In any case, 3D trigonometry converted to 2D trough orthogonal planes should solve any of your problems. Depending of the case, a polar or cylindrical coordinates system may help a bit.
