Hello,

I'm studying vertical curves in preparation for the CST III Field exam. I found a chapter on vertical alignment from the Montana Department of Transportation Road Design Manual. Example 10.5-2 is confusing me, specifically where the quadratic equation is being used. I don't see where the '400' in '400Z+/-' is coming from. The substitutions used in the discriminant are confusing to me as well. Would anyone care to help me understand how they derived their special form of the quadratic equation?

Regards,

Mark
